Research output: Contribution to journalArticlepeer-review


The Letter reports the use of novel monolithic lateral photodetectors surrounding vertical-cavity surface emitting lasers to determine the radiative transition rate and lasing threshold independent from the axial emission. The lateral detector photocurrent increases with increasing laser drive current, even as the axial emission rolls over and terminates. This clearly establishes that laser output is limited by the detuning between the Fabry-Perot cavity resonance and the gain bandwith with temperature, rather than the temperature dependence of the gain.
