Abstract
An optical pulse source includes a semiconductor diode laser, an external optical cavity, and a source of a modulated drive current such that the laser can be actively mode-locked. The external cavity includes an optical fiber and a distributed Bragg reflector. In preferred embodiments, the optical pulse source can produce pulses having a time-bandwidth product within about 20% of the transform limit, such that soliton pulses can be transmitted.
