Description/Abstract

We have experimentally realised a tunable photonic crystal microcavity with in-filling holes in silicon-on-insulator waveguide by using thermooptic effect. A thin film nichrome heater has been integrated onto the microcavity where a change in temperature (and consequent change in the refractive index of the silicon core) produced a peak resonance shift at the wavelength region = 1530 nm. A peak resonance shift of 5 nm towards longer wavelengths was achieved when the heater was switched on to a current of 1.2 mA - while maintaining high Q-factor value in the microcavity.
