Abstract

We propose a novel configuration for optical switches by the use of two coupled ring resonators acting as a phase-shifting element in a Mach-Zehnder interferometer. Because the ring structure is multi-resonant within one period of its phase response, light at any frequency within the period can be addressed by tuning the device across a small frequency interval. This enables the use of low voltages for electro-optic control of the switch, allowing for a tunable photonic switching device that operates at 1 V voltage levels. © 2005 Taylor & Francis Ltd.
