We report femtosecond pulse generation at GHz repetition rates with the Yb: YLF gain
medium for the first time. A simple, low-cost, and compact architecture is implemented for the …

In this paper, we describe generation and application of wide narrow linewidth optical
frequency combs using dual-mode injection-locking of InP quantum-dash mode-locked …

First observation of passive mode-locking in two-section quantum-dot lasers operating at
wavelengths around 1.55 μm is reported. Pulse generation at 4.6 GHz from a 9 mm long …
