Abstract
We demonstrate a micro-resonator based on a channel waveguide terminated with metallic mirrors side coupled to a bus waveguide. Transmission through such a resonant structure implemented in a silicon-on-insulator platform is investigated theoretically and demonstrated experimentally. The resonator is 13.4 mu m long, exhibits an unloaded Q-factor of similar to 2100, and a free spectral range of 21 nm around the wavelength of 1.55 mu m. (C) 2011 Optical Society of America
