Fast and low-power thermooptic switch on thin silicon-on-insulator

We have designed and fabricated Mach-Zehnder interferometer thermooptic switches using a wafer-bonded thin-silicon-on-insulator materials system. The thermally switched devices use single-mode strip waveguides with dimensions 0.26×0.6 μm 2 , operating at a wavelength of /spl lambda/=1.55 μm. Useful...

Description
Summary:We have designed and fabricated Mach-Zehnder interferometer thermooptic switches using a wafer-bonded thin-silicon-on-insulator materials system. The thermally switched devices use single-mode strip waveguides with dimensions 0.26×0.6 μm 2 , operating at a wavelength of /spl lambda/=1.55 μm. Useful device characteristics include a low switching power, 50 mW, and a fast rise time of
