Abstract-The first integrated InP-based polarization independent optical crossconnect is reported. The device can crossconnect signals at four wavelengths independently from two input fibers to two output fibers. Total on-chip loss is less then 16 dB. Device size is 7 2 9 mm 2 .

Abstract-A polarization-independent dilated switch with a low crosstalk level has been realized. In this switch, the crosstalk signal is attenuated by using controllable electrooptical attenuators which do not disturb the input signal. A reverse bias of 20 V on the attenuators reduces the crosstalk value of the dilated switch from −32 dB to −40 dB. The excess loss of the total switch is about 9 dB.

Abstract-A four wavelength 2 2 2 optical wavelengthdivision-multiplexed cross-connect with dilated switches is reported. The device is monolithically integrated on InP and consist of two eight-channel PHASAR's combined with 16 electrooptic Mach-Zehnder interferometer switches. On-chip loss is less than 017 dB and crosstalk is better than 020 dB.
