Abstract :
The equivalent thermal circuit of laser diodes plus their dissipating structures was completely characterised using a method based on the measurement of device voltage transient behaviour under pulsed bias. The experiments performed on ridge type lasers with copper submount showed the contributions of the mounting configuration and the solder layer to the thermal resistance of the structure.
