ABSTRACT:
An optical wavelength locking system is provided that includes a plurality of optical signal generating units for generating optical signals corresponding to a plurality of channels, and an optical wavelength locking unit for receiving the optical signals corresponding to the plurality of channels and sequentially controlling a wavelength fluctuation exhibited by the optical signal of each channel. Since one optical wavelength locking unit is used for a plurality of optical sources, production costs are reduced, a better utilization of available space can be achieved and the reliability of the system is improved.
