摘要：
An apparatus is provided, in which a feedback loop for tuning a tunable laser includes a Mach-Zehnder interferometer (MZI), a photodetector optically coupled to an optical output of the MZI, and an electrical feedback control circuit connected to receive electrical output signals from the photodetector and configured to frequency-adjust the tunable laser based on the received electrical output signals. One arm of the MZI includes an optical resonator to provide a frequency reference for tuning.
