Wavelength locking platform for DML-based multichannel transmitter on a silicon chip

We present a platform for the feedback control of a multichannel transmitter based on DML sources and a silicon photonic multiplexer and carver circuit. Automatic tuning and wavelength locking are demonstrated in about 150 ms.
