Research output: Chapter in Book/Report/Conference proceedingConference contribution


The development of a segmented-contact, single pass method for measuring optical gain in semiconducting quantum well structures was reported. The relation between spontaneous emission and gain spectra of excited semiconductor systems was used explicitly to derive the spontaneous emission current. The modal gain and spontaneous emission spectra for the structures were measured, and the implications of low photon energies and low temperature effects were considered for the calculations of the material system.
