Abstract :
A set of distributed Bragg Reflector mode-locked semiconductor lasers are presented that generate picosecond pulses over a spectral range of 40 nm on a single chip. The same technology is used to realize an integrated laser with two separate Bragg gratings coupled into a common gain and saturable absorption section. This laser is shown to lock together the two spectral slices from each grating in a single pulse train.
