Sub- s Switching Time in Silicon-on-Insulator Mach–Zehnder Thermooptic Switch
نویسندگان
چکیده
We have demonstrated both rise and fall times below 1 s with 10%–90% modulation in a silicon-on-insulator thermooptical Mach–Zehnder switch. The switch is based on 9m-thick and 10m-wide single-mode rib waveguides. Very fast switching was achieved by using a differential control method. The switch was driven with a digital signal processor accompanied by simple electronic circuitry.

Hybrid InGaAsP-InP Mach-Zehnder Racetrack Resonator for Thermooptic Switching and Coupling Control.
An InGaAsP-InP optical switch geometry based on electrical control of waveguide-resonator coupling is demonstrated. Thermooptic tuning of a Mach-Zehnder interferometer integrated with a racetrack resonator is shown to result in switching with ON-OFF contrast up to 18.5 dB. The optical characteristics of this unique design enable a substantial reduction of the switching power, to a value of 26 m...
