Abstract

A channel-switching add/drop multiplexer with tunable fiber grating tuned by cantilever beam is proposed and experimentally demonstrated. The device consists of two 3dB couplers and a fiber Bragg grating with 99% peak reflectivity at 1557.86nm and 0.2nm bandwidth. The grating is firmly clung on an organic glass cantilever beam and we can continuously tune the reflectivity wavelength through tuning the cantilever beam manually. The no- chirped linerly tuning signal range is about 6.1nm which may permit 7 channels with channel spacing of 0.8nm (100GHz) to insert or drop signal. A broadband light source and a 4- wavelength all fiber laser are used to test its capability in experiment. The adjacent channel isolation is not less than 23dB. The device shows good performance, but suffers from a high insertion loss.
