Reduce Footprints of Multiport Interferometers by Cosine-Sine-Decomposition Unfolding

Abstract

We present a novel 3D-unfolding method based on Cosine-Sine-Decomposition (CSD) to enable an alternative arrangement of unitary blocks towards plane normal, which reduces the planar footprints of universal multiport interferometers exponentially.

Optimal design for universal multiport interferometers

William R. Clements, Peter C. Humphreys, Benjamin J. Metcalf +2 more

Universal multiport interferometers, which can be programmed to implement any linear transformation between multiple channels, are emerging as a powerful tool for both classical and quantum photonics. These interferometers are typically composed of a regular mesh of beam splitters and phase shifters, allowing for straightforward fabrication using integrated photonic architectures and ready scalability. The current, standard design for universal multiport interferometers is based on work by Reck et al. [Phys. Rev. Lett.73, 58 (1994)PRLTAO0031-900710.1103/PhysRevLett.73.58]. We demonstrate a new design for universal multiport interferometers based on an alternative arrangement of beam splitters and phase shifters, which outperforms that by Reck et al. Our design requires half the optical depth of the Reck design and is significantly more robust to optical losses.
