    摘要: In the semiconductor laser module testing device, a temperature control power source changes a temperature of a wavelength locker module, and a wavelength monitoring bias circuit detects an output of a wavelength monitor in the changed temperature range and computes a correlation between a temperature of a semiconductor laser and a wavelength of light output therefrom. Moreover, the wavelength of the output light is locked by controlling the temperature of the wavelength locker module while feeding back the output of the wavelength monitor by a wavelength feedback circuit based on the obtained correlation between the temperature and the wavelength.

    摘要: In order to tune an oscillation wavelength of a semiconductor laser diode to a target wavelength, the amount of change of a wavelength to the amount of change of a wavelength varying item is determined by actual measurement and a basic wavelength coefficient is renewed by using the ratio of both amounts of change as a corrective wavelength coefficient, and thus the characteristic when the wavelength of an actual device is made closer to a target wavelength is utilized.
