Abstract

We have fabricated Bragg reflectors at 1550 nm in multilayer channel waveguides of As-S-Se/As-S chalcogenide glasses using near-bandgap light (˜514 nm). A reflectivitity up to 86% (˜8.5 dB), and a linewidth of ˜0.3 nm were achieved for a 3.0 mm long first order Bragg grating. The polarization dependence of these Bragg filters was also studied.
