We demonstrate a silicon electronic–photonic integrated 25 Gb/s nonreturn-to-zero transmitter that includes driver circuits, depletion-type Si ring modulator, Ge photodetector, temperature sensor, on-chip heater, and temperature controller, all monolithically integrated on a 0.25 μm photonic BiCMOS technology platform. The integrated transmitter successfully provides stable and optimal 25 Gb/s modulation characteristics against external temperature fluctuation.
