Abstract

Optical isolators and circulators are extremely valuable components to have in photonic integrated circuits, but their integration with lasers poses significant design and fabrication challenges. These challenges largely stem from the incompatibility of magneto-optic material with the silicon or III-V platforms commonly used today for photonic integration. Heterogeneous integration using wafer bonding can overcome many of these challenges, and provides a promising path towards integrating isolators with lasers on the same silicon chip. An optical isolator operating for TE mode with 25 dB of isolation, 6.5 dB of insertion loss, and tunability over 40nm is demonstrated and a path towards integrating this isolator with the heterogeneous silicon/III-V laser is described.

Figures (7)

Fig. 1
Fig. 1 Schematic of the various magneto-optic effects used to realize optical nonreciprocity for light propagating in the z-axis (a). Faraday rotation occurs when Hz,ext ≠ 0, resulting in polarization rotation. When (b) Hy,ext ≠ 0 or (c) Hx,ext ≠ 0, NRPS is present, and maximized for TE and TM modes respectively for the depicted waveguide geometries.
Fig. 2
Fig. 2 (a) Schematic of the typical heterogeneous silicon/III-V laser structure formed by direct wafer bonding. (b) The optimal Si and Ce:YIG thicknesses to maximize the NRPS for a 600nm wide waveguide [58].
Fig. 3
Fig. 3 (a) Schematic of the TE/TM polarization rotator consisting of an (b) adiabatic coupler and (c) linear taper under the Ce:YIG region. If the widths and lengths of the coupler (d) and taper (e) are chosen according, the transition can be fully adiabatic, resulting in efficient, broadband polarization rotation.
Fig. 4
Fig. 4 (a) Cross sectional schematic of the Si waveguide with the bonded Ce:YIG and integrated electromagnet. Multiple narrowly spaced coils of the electromagnet increase the magnetic field strength at the waveguide and results in larger NRPS for a given current. (b) Experimental data showing the increase in NRPS for thinner SGGG and multi-coils. Adding too many coils provides diminishing returns, as the outer coils do not contribute as much to the transverse magnetic field. NRPS increases linearly until the magnetization in the material is saturated.
Fig. 5
Fig. 5 (a) Microscope image of the microring isolator with TE/TM rotator (not shown). (b) The measured transmission spectra of the isolator with no applied current is shown in black, and compared to reference waveguides. (c) The transmission spectra of the isolator at 1549.5 nm for 40 mA of applied current showing 25 dB of optical isolation.
Fig. 6
Fig. 6 (a) Optical bandwidth of the isolator for different isolation levels. (b) The thermal (reciprocal) and MO (nonreciprocal) induced shifts on resonance wavelength with respect to applied current. Both effects can be used to tune the wavelength a full FSR in (c) while maintaining high isolation ratio. (d) The tuning allows for larger than 20 dB of optical isolation anywhere from 1540 nm to 1580 nm.
