The Effect of Temperature on the Performance of Uncooled Semiconductor Laser Diode in Optical Network

Mohammad Syuhaimi Ab-Rahman and Nurain Izzati Shuhaimi


Problem statement: The characteristics of a laser diode are highly dependent on the temperature of the laser chip. Thus, the effect of temperature on the network performance of uncooled semiconductor laser diode are studied by simulating its equivalent electrical circuit, developed from the rate equations that governing optical components directly into an electrical simulation framework. Approach: The simulations are carried out using circuit analysis program named OptiSPICE and Opti System. On this simulation study, the analysis is done based on three parameters in order to determine the quality of received signal which are; center wavelength, bandwidth and output power. Results: As the temperature variance is fed to the laser diode through an external thermal noise, the result will shows that the ambient temperature of laser diode is varied with time. In this case, the performance of laser diode will decreases as the operating temperature increases or, conversely the performance increases as the operating temperature decreases. Conclusion: The circuit design must be simulated using a SPICE engine that incorporates both electrical and optical models, which is Opti SPICE software. It cannot be simulated using traditional software packages because they do not provide sufficient coupling between electrical and optical devices.
