Abstract
In the work, the temperature noise of laser diodes caused by photon and carrier fluctuations is investigated. Therefore, the temperature generating mechanisms are considered, and temperature effects are introduced into the rate equations. The temperature noise results in an increased frequency noise, a broadened linewidth and a linewidth floor at high optical power. To reduce this effect, the thermal resistance and the thermal cutoff frequency must be minimised
