Paper Abstract

The linewidth, chirp and mode-suppression-ratio (MSR) of directly modulated sampled grating DBR (SGDBR) lasers has been measured. Although the tuning range can be up to an order of magnitude larger than in simple DBR lasers (i.e. 60 nm vs 6 nm), we find that the linewidth, chirp and MSR are about the same or better (i.e. (Delta) (nu) < 5 MHz, (alpha) equals 3-8, and MSR > 40 dB) over a wide range of operating parameters. The modulation bandwidth was in excess of 4 GHz, and the dynamic MSR remained > 40 dB as long as the current did not swing below threshold.
