摘要： An injection seed of an injection locking type light source includes a broadband light source, a seed circulator receiving and transmitting a light from the light source to a seed optical filter passing only a desired wavelength band among the light beams from the light source and passing through the seed circulator, and an injection light source receiving a light beam of a specific wavelength band passing through the seed optical filter and outputting the wavelength-locked light beam without modulation to the seed optical filter at a predetermined power. The seed optical filter receives and outputs the wavelength-locked light beam from the injection light source to the seed circulator, and the seed circulator receives and outputs the wavelength- locked light beam as a seed beam injection locking type light source which of the noise can be minimized. Since noise signal of a seed beam is small, noise signal of a final transmitting beam is also small and preferable for the high speed communication.
