Abstract :
A polarisation independent InP-based 8*8 multiplexer is realised by designing the free spectral range to exactly match the TM-TE shift. The device exhibits a channel spacing of 88.4 GHz (0.71 nm), a crosstalk of -20 dB and a channel bandwidth of 39 GHz (0.31 nm). The insertion loss is below 5 dB for all eight channels.
