Abstract

We propose and numerically simulate an integrated photonics platform to implement a compact, universal, and tunable 4×4 mode coupler for quantum information processing. We have previously developed technology for the simultaneous inscription of planar optical waveguides and Bragg gratings by direct UV writing for use in integrated photonic circuits. By providing the gratings with a tilt angle, we are able to achieve wavelength selective coupling of light between two parallel channel waveguides. Recently, we have exploited 45° tilted gratings in order to demonstrate a polarising waveguide-to-waveguide coupler using this platform.
