Abstract
Two types of polymer thermo-optic wavelength tunable filter (TOWTF) have be en developed, each with a pair of triangular phase shifters. One filter is designed for a large-scale WDM system (32 channels, 0.8 nm spacing), the ot her for a small-scale WDM system (10 channels, 0.8 nm spacing). The arrayed waveguide number is optimised thus reducing the operating power required b y the filters. Moreover, both filters operated with a low crosstalk of < -2 5 dB.
