Optical short-pulse generation using diode lasers with negative optoelectronic feedback.
A new method of optical short-pulse generation using stable diode lasers with negative optoelectronic feedback is proposed. Optical pulses with repetition rates of several gigahertz can be generated with a calculated pulse width of the order of a picosecond, and the required gain-bandwidth product of the feedback network is a few tens of gigahertz. This method does not require any external modulation signal, and it is not susceptible to critical optical alignment.
