A new Bragg grating filter (BGF) in a polysilane waveguide has been fabricated by a two-beam interferometric photobleaching method using a He-Cd laser. A narrow reflected bandwidth of 0.4 nm was measured using a 1.55-mum light-emitting diode. The temperature dependence of the BGF was measured as 0.096 nm/degC with temperature control over a range between 30 degC and 70 degC and exhibited a good coincidence with the theoretical values
