    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.

    摘要: An optical communication module includes: a laser light emitting unit that emits laser light; a temperature control unit that controls the temperature of the laser light emitting unit; a power intensity control unit that controls the power intensity of the laser light emitted from the laser light emitting unit; and a setting value storage unit that stores a setting value determined from an optimum power intensity that maintains a predetermined wavelength and satisfies predetermined temperature conditions and predetermined power intensity conditions, and from an optimum temperature that maintains the predetermined wavelength and satisfies the predetermined temperature conditions and the predetermined power intensity conditions. In this optical communication module, the temperature control unit and the power intensity control unit control the temperature and the power intensity of the laser light emitting unit, based on the setting value stored in the setting value storage unit.

    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: A device and method for controlling the temperature of a semiconductor module in which the semiconductor module is sandwiched by a first supporting unit and a second supporting unit. An area of the second supporting unit with which the semiconductor module comes into contact is shielded from heat of external ambient atmosphere, and has a temperature sensor provided thereat. The temperature of the first supporting unit is controlled so that the temperature of this area becomes equal to a predetermined temperature. The amount of heat moving from the heat-shielded area to the semiconductor module is small, so that the difference between the temperatures in the region extending from the heat-shielded area and the semiconductor module is small. The first and second supporting units may be separately controlled at different predetermined temperatures. By this, changes in the temperature of the semiconductor module caused by changes in outside air temperature are reduced. The invention aims at making the difference between the temperature of the semiconductor module and a predetermined temperature small when controlling the temperature of the semiconductor module by bringing it into contact with the supporting units whose temperatures have been controlled.
