Abstract

An optical switch is fabricated based on nanocrystalline vanadium oxide thin film with micromachining technology, and has ON state with semi-conducting phase and OFF state with metallic phase. At optical communication wavelength, its power dissipation is 15mW, extinction ratio is 14dB and switching response time is 2ms.
