We propose and investigate numerically a new kind of integrated optical waveguide coupler. Two waveguides with tilted Bragg gratings couple selectively to discrete counterpropagating cladding mode that acts as an intermediary transfer power between the waveguides. This gives highly versatile platform can act low-loss coupler arbitrary coupling ratio 0% 100%, narrow-bandwidth wavelength filter, phase-selective switch transmits two light waves fixed relative phase but reflects orthogonal...
We propose and numerically simulate an integrated photonics platform to implement a compact, universal, tunable 4×4 mode coupler for quantum information processing. have previously developed technology the simultaneous inscription of planar optical waveguides Bragg gratings by direct UV writing use in photonic circuits [1]. By providing with tilt angle, we are able achieve wavelength selective coupling light between two parallel channel waveguides. Recently, exploited 45° tilted order...
We propose and investigate theoretically the use of bi-directional propagation light in silica integrated coupled waveguide structures for linear optical processing fiber-coupled photons. show that class operations can be implemented such a system is given by symmetric unitary matrices. present how an arbitrary 4 × coupler this form realized sequence more fundamental 2 couplers single-waveguide phase shifters discuss detail implementation platform utilizing direct UV-written waveguides long-...
We have recently developed and experimentally demonstrated the technology of tilted Bragg gratings in integrated optical waveguides to achieve polarisation selective coupling between parallel waveguides. Here I will review our ideas, designs simulations for novel devices based on this platform. Multimode devices, tailored phase matching, methods significantly improved efficiencies be discussed that interest applications quantum information processing multimode telecommunication.
We propose and numerically simulate a new highly compact integrated 4x4 mode coupler based on two single-mode waveguides exploiting both forward backward propagating directions to double the number of modes. The parallel are coupled via long short-period gratings co- counterpropagating directions, respectively, single cladding device which acts as bus between waveguides. By connecting all end facets optical circulators we construct with four input output ports but only using Such can be...
