Super compact optical add-drop multiplexer for FTTH applications based on low-loss polymer waveguide materials

Four- and eight-channel arrayed-waveguide grating (AWG) and fixed optical add-drop multiplexer (OADM) devices with channel spacing of 1200 and 600 GHz have been fabricated using super-high refractive index contrast (Delta n=0.020) triazine containing polymers. Accordingly, the size of the four-channel AWG was only 10x3 mm and the insertion loss was 3 dB.
