(English Abstract)
This paper has been studied about supply of optical source of laser diode with stable and uniform output wavelength in optical transmission system. The stabilized constant current circuit is designed. The temperature control circuit is constructed for the control of internal temperature of laser diode. Also, the wavelength locker is used in optical output. Finally, A/D, D/A converter and micro-processor are used for the control of temperature.
