Abstract

The temperature greatly influences the characteristics of external cavity laser diode (ECLD). The high accurate temperature control of ECLD is one of the pivotal technologies of stable output wavelength. In this paper, the principle and method for high accurate temperature control of ECLD are described. The scheme of bistable temperature control is given, which is combined by the analog circuit with PID control theory and the digital circuit design based on microcontroller, and it is studied and analyzed.
