Wavelength-tuning-free 10-Gb/s operation of a silicon-integrated resonantly-enhanced modulator and single-mode laser

A modulator with an enhanced efficiency by cascaded microring resonators (MRRs), and a single-mode laser with a wavelength determined by a MRR wavelength filter were integrated on a Si chip to demonstrate for the first time wavelength-tuning-free 10-Gb/s modulation over a wide range of temperature.
