Abstract

Two Dimensional Integrated Optical (2DIO) structures provide extremely flexible design advantages over waveguide based devices due to ultra low crosstalk and loss between crossing optical paths. However, the truncation effects of mirror etches and beam divergence have not been analysed in detail. Effects of beam truncation are examined in order to provide methods for designing beam splitters which are required in 2DIO crosspoint switch designs. In a 2DIO 2×2 crosspoint switch architecture, input beams are truncated and split in a mirror matrix to perform the required switch logic. A Beam Propagation Model has been written in order to analyse the truncation effects of the matrix in detail. The model performs an eigen-function solution of the wave-equation to calculate the reflected propagation off a mirror truncation. The calculation reveals an optimum position for placing amplifier gate switches or further mirror etches after such a mirror truncation has taken place.
