Abstract

Control of orbital angular momentum (OAM) in optical fields has seen tremendous growth of late, with a myriad of tools existing for their creation and detection. What has been lacking is the ability to arbitrarily modify the OAM spectrum of a superposition in amplitude and phase, especially if a priori knowledge of the initial OAM spectrum is absent. Motivated by a quasi-mapping that exists between the position and OAM of Laguerre-Gaussian modes, we propose an approach for a single-step modulation of a field’s OAM spectrum. We outline the concept and implement it through the use of binary ring apertures encoded on spatial light modulators. We show that complete control of the OAM spectrum is achievable in a single step, fostering applications in classical and quantum information processing that utilise the OAM basis.

Figures (7)

Fig. 1.
Fig. 1. Concept behind our proposed OAM shaping method for any arbitrary (and perhaps unknown) initial spectrum. Step 1 involves the determination of the position-OAM mapping ($r_\ell \leftrightarrow {\left |{\ell }\right \rangle }$) denoted by the solid line and is performed theoretically (or numerically) beforehand. Step 2 corresponds to the construction of the ring apertures centred at $r_\ell$ and having a certain width $\rho _\ell - \rho _{\ell -1}$, denoted by the horizontal bands (this is also performed theoretically beforehand). Then, by specifying the amplitudes and phases of the ring apertures (step 3) and applying them collectively to the original field, any desired shaping can be elicited (such as the example shown above).
Fig. 2.
Fig. 2. Plot showing the OAM mode shaping process with LGs (top) and PVs (bottom) for an initially uniform OAM spectrum. The radial field profile of individual modes is shown in (a),(g) with vertical dashed lines denoting the boundaries of the ring apertures. The initial field, the corresponding modification hologram and the shaped field is shown in (b)-(d) and (h)-(j). The OAM spectrum before and after shaping is shown in (e),(f) and (k),(l) where the solid lines in (f),(l) denote the encoded transmittance of the ring apertures.
Fig. 3.
Fig. 3. Schematic of the experimental set-up; $L_i$ are lenses of focal length $f_i$. The left side shows the generation part of the setup with the corresponding hologram that creates the PV superposition mode. The right side depicts the modification and detection steps with the corresponding hologram (which is a product of modification and detection holograms) and 2 example images at the detection plane (small squares denote the on-axis region).
Fig. 4.
Fig. 4. Procedure for OAM spectrum correction. Shown from left to right are the experimental and theoretical raw spectra coefficients (a), correction factors (b) and corrected coefficients (c) for the decomposition of the field in Eq. (14). Raw spectra coefficients are normalised to the maximum camera gray level for the particular settings used.
Fig. 5.
Fig. 5. Experimental results showing examples of the shaping of a flat (a) and non-flat (b) OAM spectrum. All spectra have been corrected in accordance with the procedure in Fig. 4 and all $c_\ell$ values are normalised to the maximum camera gray level.
Fig. 6.
Fig. 6. Experimental OAM filtering: (a) is the initial OAM spectrum and (b), (c) and (d) are the spectra after low-pass, high pass and prime-pass filtering, respectively. Insets show the corresponding OAM filter holograms.
Fig. 7.
Fig. 7. Demonstration of the shaping of inter-modal phases for a uniform OAM superposition in $\ell \in [-5,5]$. The camera images are taken at the Fourier plane where the phase manipulations are clearly visible. Simulated OAM spectra are shown alongside where the dark lines correspond to the encoded ring aperture transmission functions. The fact that the experimental field intensities are in such good agreement with simulation gives qualitative evidence that the experimental OAM spectrum has been shaped in accordance with the simulated spectrum.
