Design and scalability analysis of optical phased-array 1 × N switch on planar lightwave circuit

Abstract

We derive explicit design rules of optical phased-array planar 1 × N switch to achieve small insertion loss, large extinction ratio, and non-dispersive waveguide structure required for wavelengthindependent broadband operation. The minimum number of phase shifters and slab lengths were studied as a function of N and the optimized array shape was derived to minimize the optical path length. We show that the length depends nonlinearly on N , and may become significantly shorter compared with that of a tree-structured switch under certain conditions.
