Abstract :
Subpicosecond optical pulses are generated by passive modelocking in bulk active layer InGaAsP semiconductor lasers under CW pumping. The saturable absorber regions are formed by deep implantation of heavy ions into the diode facets. Optical pulses with 0.64 ps width are realised at 110 GHz repetition rate without using any external AC sources. No changes In spectra and autocorrelation traces were observed after 50 h of CW operation
