摘要：

A new tunable optical notch filter for use in Wavelength Division Multiplexing (WDM) transmission system has been fabricated in the InGaAsP/InP material system for use at 1.55 mum. The device uses tunable reflection gratings in a waveguide to control the channels (4 in this case). Crosstalk levels between 9 dB and 20 dB have been measured, depending on the channel. System experiments at 150 Mb/s show less than 1 dB crosstalk penalty at 10(-9) bit-error rate.
