Abstract

In this paper, the loss and gain characteristics of optically-pumped InGaAs/GaAs quantum well lasers are measured based on the photoluminescence spectra from dual facets of a single laser device. The device is pumped by 808nm fiber coupled semiconductor lasers controlled with pulsing signal and beam shaping system to reduce the thermal effect. The result of loss spectra is consistent with gain spectra well. In addition, the special double-peak configuration in the loss and gain spectra is observed and analyzed, in term of the strain mechanism and band structure of InGaAs quantum well. The results will be very helpful to the study and design of the InGaAs semiconductor lasers
