Abstract :
Compact 1times2 wavelength multiplexer modules employing thin-film filters integrated into polymer planar waveguide circuits are presented. The modules also feature on-chip deep-etched U-grooves for precise fibre-chip coupling. Insertion loss <1 dB, crosstalk <-30 dB, and return loss <-50 dB have been achieved by various technological optimisations.
