Abstract:
1. A method of stabilizing the wavelength of light emitted by each one of a plurality of multimode diode-lasers, each of said diode-lasers having an emitting bandwidth, the method comprising the steps of: providing a wavelength selective reflecting device having a peak reflection wavelength within the emitting bandwidth of the diode-lasers; coupling the light emitted from the plurality of diode-lasers into a first multimode optical fiber; directing said light from said first multimode optical fiber onto said wavelength selective reflecting device; and reflecting a portion said light having said peak reflection wavelength from said wavelength selective reflecting device back along said first multimode optical fiber and back into said diode-lasers thereby locking the wavelength of the light emitted from said diode-lasers to said peak reflection wavelength.
