Abstract

The authors propose and experimentally demonstrate a novel technique that uses a single Fabry‐Perot laser diode (FP‐LD) to perform simultaneous all‐optical clock division and wavelength conversion. By utilizing the nonlinear dynamical period‐one oscillation and the cross‐gain modulation effect of the light injection semiconductor laser, we achieve the all optical clock frequency division of 12.36 GHz to 6.18 GHz with simultaneous wavelength conversion from 1550.24 nm to 1545.91 nm. The phase noise of the extracted optical clock is less than −105 dBc/Hz. It was empirically found that the best clock division and wavelength conversion occurred when the injected signal power was approximately 2–2.5 times as the injected probe light power, and the range of optimum wavelength detuning was about from −0.01 nm to 0.06 nm. © 2009 Wiley Periodicals, Inc.

## Abstract This paper presents the design of a low‐timing‐jitter, stable picosecond optical‐pulse source, which is based on a low‐cost, uncooled Fabry–Perot (FP) semiconductor laser in the gain‐switching operation. The wavelength of the designed laser can be tuned from 1538 to 1554 nm under the co
