Abstract: For optical transmitters in DWDM network systems, a method of operating the semiconductor laser which provides the output of the optical transmitter. The output power and wavelength of the semiconductor laser is set by controlling the bias current and operating temperature according to a closed theoretical mathematical form. The form has the variables of output power, wavelength, bias current and temperature related to each other by empirically determined coefficients. In this manner the optical transmitter can efficiently vary its output power while maintaining its wavelength constant, or vary its wavelength while maintaining its output power constant.
