We report the use of Fano resonances as compact optical switches by exploiting their sharp asymmetric lineshape together with thermo-optic effects. This enables low footprint and efficient on chip integrated systems. The device consists of a photonic crystal (PhC) membrane with a waveguide side-coupled to a nanocavity surrounded by a p-i-n junction. We demonstrate the thermal tuning of an asymmetric Fano resonances with low power requirements and a response time of 16.1µs. Their high extinction ratio and close spectral separation between maximum and minimum of transmission makes Fano resonances suitable candidates for such optical switching.
