Passive modelocking of InGaAsP/InP laser diode over wide operating temperature range
The passive modelocked operation of an InGaAsP/InP laser diode, with a novel design of adaptable saturable absorber, up to an operating temperature of 75°C, is reported. To the authors' best knowledge, this is the first demonstration of high-temperature operation of a passively modelocked laser diode. The effect of the operating temperature on the operating frequency and the tuning range is described.
