.Thermal analysis of laser diode module by an equivalent electrical network method[J].Optoelectronics Letters,2006,2(4):273-277 Thermal analysis of laser diode module by an equivalent electrical network method YANG Ming-wei XU Wen-hai TANG Wen-yan [1]School of Electrical Engineering and Automation,Harbin Institute of Technology,Harbin 150001 ,China [2]School of Information Technology, Dalian Maritime University, Dalian 116026, China Abstract:       An equivalent electrical network method is presented in this paper to analyze the cooling characteristics of a laser diode module (LDM). And a modified equivalent model of a thermoelectric cooler (TEC) with an adjunctive thermal resistance and a contact resistance is proposed. The performance of a commercial TEC has been simulated. The thermal analysis of a LDM incorporated with a TEC has been performed by using an equivalent circuit model of the LDM. In the analysis the change of LD current, TEC current, and the ambient temperature are all considered. It shows that the equivalent circuit approach is an offective tool for the qualitative analysis of TEC and LDM. Hits: 3627 Download times: 146 View Full Text    Download reader
