Abstract
Passively mode-locked semiconductor lasers are very promising as clock generators for ultrahigh bit rate optical transmission and data processing systems due to their ability to generate picosecond and subpicosecond optical pulses at high repetition rate.1–3 The saturable absorber inside the laser diode cavity, which is required for passive mode-locking, can be formed by deep implantation of heavy ions into the cleaved facets. Previously this method was used for passive modelocking in single quantum well AlGaAs laser diode.3
