Abstract :
An optical multichannel controller that gives full access to 12 individual wavelength channels is reported. The device consists of two waveguide grating routers integrated with semiconductor optical amplifiers. It exhibits a channel spacing of exactly 3.2 nm (400 GHz) and an off-peak signal rejection of more than 40 dB. The amplifiers compensate for the multiplexer insertion losses
