Stable picosecond pulse generation at 46GHz by modelocking of a semiconductor laser operating in an optoelectronic phaselocked loop

摘要

The authors show that using a phaselocked loop, stable optical pulses can be generated from a monolithic, passively modelocked semiconductor laser. A phase noise of -100dBc/Hz at 46GHz and a pulse width of 1.3ps are achieved, and the limits of the pulse stability using this approach are discussed.
