Phase noise reduction in semiconductor lasers by optical negative feedback

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Phase noise of a single mode semiconductor laser is reduced drastically by introducing a newly proposed optical negative feedback scheme. Proof-of-concept experiment confirms that the spectral linewidth of a semiconductor laser can be reduced to 1/1,000 successfully by applying the scheme.
