| 英文摘要 | A WDM optical transmission apparatus of the present invention comprises: a light source (1) for generating light whose wavelength is changed according to the temperature and a drive current; a temperature control section (4) for controlling the temperature of the light source so that a wavelength at the starting of emission of the light source is stabilized in an allowable range of optical output wavelength set in advance; a drive current control section (5) for controlling the drive current applied to the light source according to the allowable range of the optical output wavelength; a wavelength control section (3) for detecting a wavelength of light output from the light source and controlling the temperature of the light source based on the detection result, to lead the optical output wavelength into the vicinity of a predetermined target wavelength; and an operation control section (6) for controlling the start and stop of the control operation of each section at predetermined timing respectively corresponding to the time of optical output generation and the time of optical output stop. |
