Paper Abstract

The thermal behaviour of wavelength demultiplexers, integrated on InGaAlAs epitaxially grown by MBE on InP, is reported. The overall performance is due to the superposition of two mechanisms: a pure thermooptic effect, which allows a tuning of the order of 1 A/°C, and an elastooptic effect, caused by induced stress, which can lead to much higher temperature sensitivity, up to 1 nm/°C or more.
