Abstract: A simple and successful technique for realising an athermal silica-based arrayed-waveguide grating (AWG) is described. By applying strain to the waveguide using a bimetal plate, the centre wavelength shift caused by the thermo-optic effect is cancelled out by the strain-optic effect. The wavelength shift is smaller than 0.05 nm between 25 and 77°C for an AWG chip attached to a bimetal plate.

Athermal silica-based arrayed-waveguide grating multiplexer
TL;DR: In this article, a temperature dependent channel wavelength shift in a silica-based arrayed-waveguide grating multiplexer was successfully suppressed from 0.95 to 0.05 nm in the 0-85/spl deg/C temperature range, which can be used in practical WDM systems without the need for temperature control.
