Abstract :
We present a crosstalk (CT) optimized digital optical switching matrix (4/spl times/4) based on the oversized rib waveguide concept in polymers utilizing redundant switches in the matrix configurations and tapered waveguide crossing sections yielding an average CT of -42 dB (all CT values below -30 dB) without any additional space requirements (on a 4-in wafer).
