Digital Object Identifier 10.1109/LPT.2004.823717 Fig. 1. Schematic arrangement used to obtain athermal operation of R-AWG. The mirror was fabricated in 800-m-thick Si wafer. It was approximately 20 mm long and 16 mm wide. The triangular aperture was 5 mm wide at the top. The brass rod had a cross section of 1 mm and was 10 mm long.

N2 - We present a new approach to temperature compensation of silica-based arrayed-waveguide grating multiplexers. An external mirror rotating with temperature at a constant rate, in combination with a reflective multiplexer, is used to compensate for the temperature-induced change of the refractive index, and the resulting wavelength shift of individual channels, making the device athermal. A wavelength-temperature slope of less than 3.2 times; 10 -4 nm/°C was obtained in the temperature range 5°C-70°C, without noticeable degradation in the device performance.
