Abstract

The temperature dependence of damping in quantum‐well lasers has been investigated. The lasers with large K factors at room temperature show a rapid increase of the K factor with temperature. The temperature dependence of the K factor is larger for lasers with wider separate confinement heterostructure region, fewer wells, and narrower quantum‐well width. The carrier transport in quantum‐well structures is responsible for the excess increase of the K factor at high temperatures.
