摘要
A compact low-loss polarization independent 8 x 8 PHASAR demultiplexer is presented. Device size is 0.93 x 0.75 mm(2). 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 crossconnects, add-drop multiplexers and multiwavelength lasers.
