Summary form only given. Recently, room temperature cw operation of 1.55 /spl mu/m InGaAsP MQW DBR VCSELs has been achieved for the first time. At higher temperatures, laser operation is restricted by internal losses including intervalenceband absorption and carrier leakage. Measured characteristics are simulated using a comprehensive numerical model to analyze those losses in detail and to optimize the VCSEL design.
