Abstract
Provided is an apparatus for stabilizing a wavelength for optical communications which includes a digital control circuit unit and an analog control circuit unit to stabilize a wavelength that may be shifted at the time of driving an optical source for optical communications. The wavelength can be precisely controlled according to a modulation format using the optical source for optical communications, and thus performance can be stabilized.
Claims7
An apparatus for stabilizing a wavelength for optical communications that stabilizes a wavelength of an optical source, the apparatus comprising:
- a digital control circuit unit for receiving optical intensity measurement value information and wavelength measurement value information from the optical source, receiving temperature status information from an analog control circuit unit, and transmitting various information signals to the analog control circuit unit;
- and
- the analog control circuit unit coupled to the digital control circuit unit, for receiving temperature measurement value information from the optical source, transmitting the temperature status information on the basis of the received information, and transmitting a current control signal and a temperature control signal to the optical source on the basis of the various information signals.
