Abstract:
An optical processing device for converting a wavelength of an optical signal comprises an optical processing unit supplied with an input optical beam carrying thereon one or more optical signals with respective wavelengths that are different from each other, the optical processing means being further supplied with a control optical beam having a stabilized reference wavelength and selecting the optical signal that has a first wavelength and outputting the same with a second wavelength that is specified by the reference wavelength; and a control unit for controlling the optical processing unit by specifying the first wavelength of the optical beam to be selected.
