Optical wavelength converter control method and device

U.S. Patent Number: 5345455

Abstract: An optical wavelength converter has an optical signal input adapted to receive an optical signal whose wavelength is to be converted, an optical signal output adapted to emit an optical signal whose wavelength is the required wavelength, after conversion, and at least one control electrode for applying at least one electrical signal to control the wavelength of the output optical signal. The converter is controlled by a method which comprises a calibration phase for establishing a law linking at least one of said control electrical signals to said required output wavelength and storing said law in a storage device, and an operative phase for addressing said storage device using the required output wavelength and numerical-analog conversion of the data from the storage device addressed in this way for application to said control electrode(s).
