Abstract :
A tunable WDM-channel group drop filter (WCGDF) is proposed. The filter is based on a new arrangement, which consists of an arrayed-waveguide grating multiplexer with the minimum number of inputs/outputs and optical gate switches. The spectral response of a 1.5 μm tunable WCGDF with a 0.8 nm spacing is successfully obtained and operation in accordance with the design is confirmed
