The thermo-optic coefficient (TOC) of hydrogenated amorphous silicon (a-Si:H) has been measured in the temperature range 30-200 °C, at the communication wavelength of 1.55μm. The experimental data have been fitted using a single oscillator model that takes into account the shape of ε2-spectrum of the amorphous semiconductor. The extracted parameters significantly extend, and are consistent with, the few data reported in the literature. An interesting analogy with crystalline silicon (c-Si) is also found and discussed. © 2002 Elsevier Science Ltd. All rights reserved.
