Accelerating switching speed of thermo-optic MZI silicon-photonic switches with "turbo pulse" in PWM control
OFC, pp. 1-3, 2017.
We implemented a novel heater control scheme with high-energy header pulses applied to silicon Mach-Zehnder switches. Four to five times faster switching time (5.8 μs and 4.4 μs) was achieved for heating-up and cooling-down operations.
