Abstract

We report unprecedentedly high output powers measured from large area two-dimensional square-lattice photonic-crystal band-edge lasers (BELs), patterned by holographic lithography. In order to ensure mechanical rigidity, the BELs were fabricated in an InP-based epilayer bonded onto a fused silica substrate beforehand. The BEL devices, employing the surface-emitting Γ-point monopole band-edge mode, provide a fiber-coupled single mode output power as high as 2.6 mW and an external differential quantum efficiency of ~4%. The results of a three-dimensional finite-difference time-domain simulation agree with the experimental observation that the large BELs are beneficial for achieving both high power output and high differential quantum efficiency.

1. Introduction

Compound semiconductors that incorporate photonic crystal (PC) structures have created a new paradigm for fabricating compact coherent light sources. In particular, substantial efforts have been devoted to the development of efficient PC lasers, in which the lasing mechanism relies on strongly confining photons inside a nano-scale cavity [1], or on the gain enhancement at photonic band-edge modes [2]. As far as output power is concerned, however, PC lasers have yielded only modest results to date. On the contrary, optical powers greater than 50 μW are typically required for an on-chip photonic receiver operated at a high speed (10 GHz) and a low bit-error rate (10−12) [3]. Recently, a few research groups have achieved powers in that level with different PC laser systems: an array of coupled cavity lasers [4], a line cavity edge-emitting laser [5], or a surface-emitting band-edge laser [6].

Here we report the operation of a PC laser with an unprecedentedly high mW-level fiber-coupled output. To achieve the high laser power output, we used a band-edge mode (not a cavity mode) that is spatially extended over a large area. Since the band-edge mode relies on a perfectly periodic PC pattern, we used laser-holographic lithography (LHL) method to fabricate the band-edge lasers (BELs) over a large area (typically 1×1 cm2). Unlike electron-beam lithography, intrinsically an extremely low-throughput process, the LHL method has shown to be useful for fabricating PCs or PC lasers with a high throughput [7, 8].

2. Design and fabrication

Figure 1(a) shows the schematic diagram of the PC BEL used in this study. An InP-based multiple quantum well (MQW) slab was grown by molecular beam epitaxy. It is nominally 230-nm-thick, consists of four InAsP MQWs separated by InP barriers, and has a central emission wavelength of ~1550 nm. Underneath the MQW layer, an InGaAs etch-stop layer was grown for selective chemical etching. The first step in the fabrication process was to bond the InP wafer onto a fused silica substrate, with the InAsP/InP MQW layer facing down. Then, the InP substrate and InGaAs etch-stop layer were selectively removed in dilute HCl and FeCl3 solutions, respectively [9]. A 50-nm-thick silicon nitride hard mask layer was deposited onto the bonded epilayer by plasma-enhanced chemical vapor deposition. In order to generate a square-lattice air-hole array pattern, the two-beam LHL process was applied twice, with the sample rotated by 90° before the second exposure. More details about the LHL process are given in Ref. 8. Reactive-ion etching was then performed to transfer the PC patterns into the hard mask layer and subsequently into the InAsP MQW layer. A photographic image and a scanning electron microscope (SEM) image of a fabricated BEL device are shown in Figs. 1(b) and 1(c). Note that the blue-color features in the photograph, produced by diffraction in the square-lattice PC pattern, are uniformly distributed over ~1 cm2, indicating the ability of the LHL process to produce patterns over a large area. The SEM image demonstrates the high quality of the PC patterns generated by LHL.

We employed a Γ-point band-edge because its surface emission characteristics are ideal for direct fiber coupling. Figure 2 shows the band structure calculated by the three-dimensional (3D) plane-wave-expansion (PWE) method. In this calculation, we assumed the refractive indices of the InP slab and of the fused silica substrate to be 3.17 and 1.45, respectively. Three distinct band-edges appear at the Brillouin zone center (the Γ-point), which correspond to the monopole, quadrupole, and dipole modes. The insets in the figure show the magnetic field profiles for the three band-edge modes, which were calculated by the 3D finite-difference time-domain (FDTD) method. From the band structure which was calculated for the hole radius of r = 0.2a, we determined the lattice constant to be a = 610 nm so that the monopole mode overlaps with the gain peak of the MQWs. We intended the monopole mode to lase because it has the highest quality factor among the three Γ-point band edges [10].

3. Measurements

We built a compact PC BEL system by coupling the device to a 1×2 wavelength-division-multiplexing (WDM) coupler with a single butt-end fiber tip, as shown in Fig. 3(a) . The BEL device was optically excited using a 980-nm laser diode in pulsed mode (20-ns pulse width and 1% duty cycle). Unlike our previous study [6], we used a multimode WDM fiber coupler (Fiberer Corporation, China) composed of a fiber with a 50-μm core diameter for pumping over a large area, in order to achieve a high output power. The optical excitation of the BEL and light collection of the BEL output were accomplished simultaneously by the butt-end multimode fiber tip. The fiber tip was brought to the sample until a gentle physical contact was made. The combination of a large fiber core diameter (50-μm) and a small distance between fiber tip and the device surface (< 10-μm) ensured a high fiber coupling efficiency. A narrow beam divergence angle of the Γ-point BEL also helped keeping the high fiber coupling efficiency [9]. From an independent but direct reflectance measurement of gold mirror using the same fiber coupling setup, we could estimate the fiber coupling efficiency to be greater than 90%, which was also confirmed by numerical model calculations. The BEL emission was then fed into either an optical power meter or an optical spectrum analyzer for characterization. Figure 3(b) shows the lasing spectrum of the BEL device. In addition to the sharp lasing peak at ~1510 nm, the emission spectrum exhibits two more distinct modes at shorter wavelengths. From the comparison with the calculated band-edge positions (Fig. 2), we can assign the dipole, quadrupole, and monopole modes to the peaks at 1410 nm, 1470 nm, and 1510 nm, respectively. Thus we can conclude that the BEL lased in a single mode (specifically at the monopole band-edge mode, as we intended), with the side-mode-suppression ratio greater than 40 dB.

The measured relationship between light-in and light-out (L-L) is shown in Fig. 3: (c) for low excitation levels and (d) for the entire excitation range. The excitation power at the laser threshold is ~8 mW in terms of power incident on the MQWs, rather than the power absorbed by the MQWs. The fiber-coupled BEL output power was as high as ~2.6 mW, which was limited by the maximum pump power available (~400 mW). To our knowledge, this laser output far exceeds the achievement of any kind of PC lasers reported to date, excluding surface-modulated grating based lasers [11].

4. Differential quantum efficiency versus pattern size

The differential external quantum efficiency (ηDQE), which indicates the overall combined efficiency of both pumping and photon harvesting, is defined as

ηDQE=ΔNoutΔNin=ΔPout/ωBELΔPin/ωp=ΔPoutΔPinλBELλp,
where Nin is the number of pump-laser photons that are fed into the system per unit time interval, and Nout is the number of BEL photons that are coupled to the fiber per unit time interval; ωp (λp) and ωBEL (λBEL) are the frequencies (wavelengths) of the pump laser and BEL, respectively; and is the reduced Planck’s constant. Assuming that 20% of the pump power is absorbed by the MQWs [12], we obtain ηDQE ≈ 4% by substituting the experimental values (measured at the output power of ~1 mW) into Eq. (1). In contrast, when the L-L measurement was repeated with a single mode fiber coupler (with a core diameter of only 9 μm), ηDQE is only 1.3%, i.e. much smaller than the 4% obtained for the multimode fiber coupler. This dependence of ηDQE on the pump area can be understood qualitatively as follows. In principle, all the band-edge photons within an infinitely large PC structure can be completely coupled out in the vertical direction. On the contrary, a band-edge mode in a finite-size PC structure suffers from lateral loss and therefore only a fraction of band-edge photons can be coupled out to free space [12]. Therefore, using a multimode fiber (or pumping over a large area) is crucial for achieving a high power output with a BEL. It should be noted that, although our BELs have an effectively infinite size (~ 1 cm2) as far as the patterned area is concerned, they are nonetheless finite in reality, since the MQWs outside the pumped area behave as absorbers. There may also be other reasons for the reduction in differential quantum efficiency when employing a single mode fiber, such as mode mismatch and diffraction loss, which degrade light coupling to fiber.

The 3D FDTD method was used to simulate the BEL performance, using a MEEP package developed at MIT [13]. The magnetic-field intensity profiles of the monopole BEL mode are shown in Figs. 4(a) and 4(b), which clearly demonstrate that more photons are lost laterally than are extracted in the vertical direction. The simulations indicate that lateral loss decreases monotonically with increasing PC pattern size. To analyze this quantitatively, we calculated the quality factor of the BEL as a function of the pattern size. We can also estimate the ηDQE using the theoretical equation [14]:

ηDQE=Qv1Qt11(nSiO2/nair)3+1ηiηc.

The total quality factor, Qt, is composed of the vertical and lateral quality factors, Qv and Ql: Qt −1 = Qv −1 + Ql −1. The ratio of refractive indices nSiO2 and nair accounts for differences in the speed of light in fused silica and in air in the vertically asymmetric BEL structure, and ηi and ηc are the internal quantum efficiency and the fiber coupling efficiency, respectively. Figure 4(c) displays how the quality factors (Qv and Qt) and their ratio Qt/Qv change with increasing PC pattern size. As the lateral length of the PC increases, Qv, Qt, and Qt/Qv all increase accordingly. These simulation results imply that Ql increases faster than Qv. As a consequence, ηDQE increases with the PC pattern size, consistent with the previous qualitative but intuitive argument. Assuming approximate values ηi ≈ 80% and ηc ≈ 90%, Eq. (2) gives ηDQE ≈ 5.3%, in reasonable agreement with the experimental value, 4%.

5. Conclusions

In conclusion, we have fabricated large-area square-lattice PC BELs using laser-holographic lithography and demonstrated their output power to be as high as 2.6 mW at room temperature. For stable laser operation over a large area, the BELs are bonded onto a fused silica substrate. A high external differential quantum efficiency of ~4% was obtained from a BEL of ~50 μm in diameter. We also investigated the properties of the BELs using the 3D FDTD method. Experimental and simulation results are in agreement, in the sense that the differential quantum efficiency increases in proportion to the BEL size.
