Details of the design and successful fabrication of polarisation insensitive monolithic 2/spl times/2 crosspoint switches on InP are presented, which include SOAs, electroabsorption modulators (EAMs), passive multimode interference (MMI) couplers and passive waveguides all fabricated monolithically from a single InP wafer using quantum well intermixing (QWI) processing. Results showing the performance of individual components are presented. Highlights include the achievement of 20 dB extinction ratio EAMs for a 2V swing, and passive waveguide propagation losses below 12 dB cm/sup -1/. In addition initial test results will be presented on the switching characteristics of the complete 2/spl times/2 crosspoint switch
