| 英文摘要 | A wavelength independent wave-locker arrangement is used to control the output wavelength of a laser diode. In the wave-locker arrangement, a narrow-band power splitter is responsive to the reception of a portion of an optical output signal from the laser diode for splitting the received optical signal into first and second coupler optical output signals, respectively. First and second photodetectors are coupled to receive the first and second coupler optical output signals, respectively, and generate respective corresponding first and second electrical output signals. A control unit is responsive to the reception of the first and second electrical output signals from the first and second photodetectors for generating predetermined control signals to the laser diode for maintaining the wavelength of the laser diode at a predetermined constant value. |
