Channel-Switching add/Drop Multiplexer With Tunable Fiber Bragg Grating Based on the Cantilever Beam

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 l557.86nm, and a 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 linearly tuning range is about 6.lnm, 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.
