Abstract

Optical communications usually require precise temperature control systems as junction temperature may dramatically influence the emission parameters of a laser diode. Recently, challenging optical applications, such as micro-satellite or underwater monitoring, need for small and low power solutions making it difficult to use complex temperature control systems. Accordingly, in this paper we explored the use of a small and passive copper heat sink to control the temperature and stabilize the transmission of GaN laser diode emitting around 450 nm. The results of a reliable thermal characterization for the various operating conditions showed the effectiveness of this simple solution.
