Abstract
This paper has been studied about the design of optical transmitter with stable output wavelength in WDM transmission system. The stabilized constant current circuit is designed with deviation less than 10$\mu$A. 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 these.
