Abstract

An InAs quantum-dot external-cavity passively modelocked laser with an operation wavelength of 1.27m is demonstrated, based on a two-section quantum-dot superluminescent diode with bending ridge waveguide and a 96 output coupler. Stable modelocking with an average power up to 60mW was obtained at a repetition frequency of 2.4GHz. This performance corresponds to a 25pJ pulse energy obtained directly from the oscillator, which represents a 55-fold increase in pulse energy when compared to the current state-of-the-art for semiconductor lasers. At a repetition frequency of 1.14GHz, picosecond optical pulses with 1.5W peak power are also demonstrated, representing the highest peak power achieved from an external-cavity laser at the 1.3m waveband, without the use of any pulse compression or optical amplification.
