Optical gain in GaAsBi/GaAs quantum well diode lasers

Optical gain, absorption and spontaneous emission spectra for GaAs 0.978 Bi 0.022 /GaAs laser diodes are measured experimentally and compared with theory. Internal optical losses of 10-15 cm -1 and peak modal gain of 24 cm -1 are measured at threshold. The results of calculations showed excellent ag...

Summary:Optical gain, absorption and spontaneous emission spectra for GaAs 0.978 Bi 0.022 /GaAs laser diodes are measured experimentally and compared with theory. Internal optical losses of 10-15 cm -1 and peak modal gain of 24 cm -1 are measured at threshold. The results of calculations showed excellent agreement with the experiment, key for future laser design.
