Abstract

The chirping characteristics of an injection-locked semiconductor laser have been investigated. The frequency chirp of an injection-locked semiconductor laser has three contributions—dynamic, DC, and OIL chirp. It is greatly reduced since the OIL chirp is compatible to the DC and dynamic chirp, but different in sign. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 374–377, 2000.
