Chirp investigation of monolithic mode locked laser diode pulses with a spectral domain interference method

Summary form only given. The knowledge of the phase of mode locked semiconductor laser pulses is of prime importance since applications in optical telecommunications require chirp free, transform limited pulses. Pulse phase measurements have attracted considerable interest and have been applied to external cavity mode locked laser diodes. We extend an interferometric setup proposed by to a highly sensitive and real-time method and apply it for the first time to pulses from a monolithic hybrid mode locked laser diode (MLLD).
