Frequency modulation and linewidth of gainhyphen;levered twohyphen;section single quantum well lasers

摘要

The lsquo;lsquo;gain leverrsquo;rsquo; effect in twohyphen;section single quantum well lasers can be used in enhancing the frequency modulation (FM) efficiency of the laser without a corresponding increase in the FM noise, i.e., linewidth. Theoretical and experimental results of the FM efficiency, speed, tuning range, and linewidth will be discussed and compared to other tunable laser structures.
