Abstract :
The crosstalk of an arrayed-waveguide grating multi/demultiplexer was reduced by employing a phase compensating plate developed for static phase control. Experimental results showed low crosstalk values of -37 and -39 dB for the TE and TM modes, respectively, in an 8×8 100 GHz-spacing arrayed waveguide grating multi/demultiplexer. This novel method offers polarisation independent phase control for a closely arranged waveguide array
