Abstract :
An InP-InGaAsP 4/spl times/4 optical crossconnect occupying only 2/spl times/2 mm/sup 2/ was demonstrated by combining 16 1/spl times/2 optically amplified suppressed interference switches (OASIS) in a square array architecture. On/off ratios of 33/spl plusmn/4 dB were measured by a majority of these elements and fiber-to-fiber insertion loss of 3 dB was obtained using additional on-chip amplification stages.
