Abstract :
A 0.8 nm spacing polymeric arrayed-waveguide grating (AWG) multiplexer operating around 1550 nm is realised using a silicone resin waveguide. The AWG multiplexer has an insertion loss in the range 9-13 dB, a crosstalk of <-20 dB, and a polarisation-dependent wavelength shift of 0.35 nm. The transmission peak wavelength is tunable over 10 nm with a temperature change of 55°C
