Stabilization of the Absolute Frequency and Phase of a Compact, Low Jitter Modelocked Semiconductor Diode Laser
Abstract
This research project was aimed at the stabilization of the frequency and phase of a set of optical combs from a semiconductor laser operating in an active mode-locked regime. To achieve this, an intracavity Pound-Drever-Hall technique was used on a 10 GHz harmonically mode-locked semiconductor ring laser and obtained a simultaneous optical frequency comb stabilization within 3 MHz range and supermode phase noise suppression. Together with an additional phase-lock-loop, the timing jitter integrated from 10 Hz to 10 MHz (5 GHz) was 63.5 fs (161 fs). Approximately 25 fsec of the integrated noise is attributed to line noise, resulting in a net jitter of 38 fsec. This work represents, to our knowledge, the first stabilized modelocked diode laser using PDH that achieves both supermode elimination and optical frequency comb stabilization. The resulting optical comb source may be useful for advanced RF imaging radar for optical sampling in ADC or in novel waveform generation (DAC's).
