Abstract

We propose a new design for introducing a tunable chirp on a uniform fiber Bragg grating by a controllable temperature gradient. The device consists of an unchirped Bragg grating in a bare fiber that is mounted in a plastic sleeve whose surface is coiled with a length of wire heater. The desired temperature distribution produces a chirp on the grating and at a rate that can be adjusted by varying the current. We have demonstrated an electrically tunable chirped sampled fiber Bragg grating that enables a tuning range of chirp rate up to 0.4nm/cm with an electrical power of 3.3 W.
