Optoelectronic properties of coupled cavity semiconductor lasers.
01 January 1984
Differential voltage current characteristics of coupled-cavity semiconductor lasers are studied experimentally. Lasing thresholds of individual cavities, regions of single-mode or multi-mode oscillation, or mode hop locations are easily obtained from the analysis. In addition, pumping conditions for zero net gain of a cavity can be readily determined. The optoelectronic properties can be used for monitoring operating states of the lasing system without requiring external optical elements.
