Wide-temperature-range, 25-Gbps error-free operation of integrated silicon photonic transmitter using wavelength-controlled micro ring modulator

We investigated wavelength-control-characteristics of a silicon photonic transmitter employing heater-integrated silicon micro-ring-modulator and flip-chip integrated CMOS driver. A novel wavelength control successfully demonstrated error-free operation at 25 Gbps during wide-package-temperature cycle between 20 and 60 degrees C for the first time.
