Abstract

The authors demonstrate a compensation scheme to reduce the frequency chirp associated with directly modulated sampled grating distributed Bragg reflector tunable lasers. Experimental results obtained show that the direct modulation of the laser's gain section results in a large frequency chirp of 25 GHz. However, by simultaneous modulation of the laser's phase section this large frequency chirp can be significantly reduced.
