Silicon Waveguides and Ring Resonators at 5.5 μm
Published 17 Aug 2010 in physics.optics | (1008.2978v1)
Abstract: We demonstrate low loss ridge waveguides and the first ring resonators for the mid-infrared, for wavelengths ranging from 5.4 to 5.6 {\mu}m. Structures were fabricated using electron-beam lithography on the silicon-on-sapphire material system. Waveguide losses of 4.0 +/- 0.7 dB/cm are achieved, as well as Q-values of 3.0 k.
