We have fabricated Bragg reflectors at 1550 nm in multilayer channel waveguides of As-S-Se/As-S chalcogenide glasses using near-bandgap light (similar to 514 nm). A reflectivitity up to 86%(similar to8.5 dB), and a linewidth of similar to0.3 nm were achieved for a 3.0 min long first order Bragg grating. The polarization dependence of these Bragg filters was also studied.
