Polarization independent dilated WDM cross-connect on InP
A four wavelength 2×2 optical wavelength-division-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 -17 dB and crosstalk is better than -20 d
Low-loss, compact, and polarization independent PHASAR demultiplexer fabricated by using a double-etch process
A compact low-loss polarization independent 8 x 8 PHASAR demultiplexer is presented. Device size is 0.93 x 0.75 mm2. On-chip losses are less than 4 dB and crosstalk is better than - 20 dB. The device is suitable for integration with electro-optical switches for application in integrated optical crossconnets, add-drop multiplexers and multiwavelength lasers
