The analysis of thermal characteristics of the laser diode by transient thermal response method
Using the terminal voltage method, we measured and analyzed the thermal characteristics of the laser diodes (LD). From heating response curves, it is possible to determine the thermal resistance, R/sub th/ of different layers of the packaged LDs. The dependence of the R/sub th/ on the working current was measured. It shows much difference between below and above threshold current. This gives much information about the coupling between thermal and optical properties.
