摘要： An optical system has a transmission filter device, a feedback mechanism, and one or more radiation sources. Each radiation source generates an output signal with a predetermined wavelength band and polarization and is coupled to a separate input port of the transmission filter device. The transmission filter device, which is responsive to output signal from each radiation source, generates an output signal from at least one output port thereof. The feedback mechanism is coupled to at least one output port of the transmission filter device for providing a feedback signal that is directed back through the transmission filter device to each of the radiation sources for stabilizing each of the radiation sources. The apparatus is polarization maintaining wherein the one or more radiation sources, the transmission filter device, and the feedback mechanism are interconnected such that principle axes of polarization thereof are substantially aligned.

摘要： In an optical device, each of a plurality of radiation sources generates a separate different wavelength output signal to a wavelength locking device wherein a grating device receives the separate wavelength output signals from the plurality of radiation sources. The grating device generates a multiplexed wavelength output signal at a zero diffraction order output port thereof, and resolves separate symmetric wavelength+δ and wavelength−δ output signals at separate predetermined locations within at least one non-zero diffraction order thereof for each of the radiation sources. Each of a plurality of radiation detectors is coupled to receive a separate one of the symmetric wavelength+δ and wavelength−δ output signals and generate an output signal representing the magnitude of the received wavelength output signal. A control device is responsive to output signals from each pair of radiation detectors coupled to receive the separate symmetric wavelength+δ and wavelength−δ output signals from a specified predetermined radiation source for generating an output control signal appropriate to that radiation source for locking the wavelength thereof.

摘要： In a stabilized laser system, an output of a desired wavelength is generated. Each of a plurality of n lasers, which, while emitting light and having a preselected portion thereof fed back thereto, causes the fed back portion to be amplified and shifted in wavelength in a first direction which is spaced apart from the center wavelength of the feedback signal. A feedback stabilization arrangement is coupled to output ports of the plurality of n lasers for generating a feedback signal having a wavelength spectrum peaking at a wavelength shifted in an opposite direction to the first direction generated by the lasers in response to the feedback signal so as to provide an output signal at the output of the stabilized laser system having a wavelength spectrum that peaks essentially at the desired wavelength. A reflector is located at a predetermined signal round-trip time delay distance from the feedback stabilization arrangement. The reflector receives the output signal from the feedback stabilization arrangement and passes a first portion thereof therethrough, and reflects a remaining second portion back to the feedback stabilization arrangement as a secondary feedback signal that contributes to each of the plurality of n laser sources being set in a stable coherence collapse mode.

摘要： In a stabilized laser system, a signal is to be generated at an output thereof having a desired central wavelength. At least one laser, which, while emitting light and having a preselected portion thereof fed back thereto, causes the output signal of the at least one laser source to be shifted in wavelength in a first direction which is spaced apart from the center wavelength of the fed back signal. A feedback generating arrangement is coupled to the at least one laser to process a first portion of the output signal from the at least one laser and generate a feedback signal having a spectral response peaking at a wavelength shifted in an opposite direction to the first direction generated by at least one laser. The feedback signal that is shifted in the opposite direction causes the at least one laser to provide an output signal at the output of the stabilized laser system having a spectral response that peaks essentially at the desired wavelength.

摘要： A basic reflector arrangement has first and second power splitters. The first power splitter has first, second, third, and fourth ports where the first port is coupled to a remote signal source for receiving signals therefrom and providing feedback signals thereto. Signals received at each of the first and fourth ports are combined and split into first and second portions for transmission via the second and third ports, respectively, and signals received at the second and third ports are combined and split into first and second portions for transmission via the first and fourth ports, respectively. The second power splitter has first, second, third, and fourth ports, where the second port is coupled to provide an output signal from the reflector arrangement, and the first, third, and fourth ports are coupled to the second, third, and fourth ports, respectively, of the at least one first power splitter. Various components such as transmission filters, filter/multiplexers, and delay lines can be added in paths coupling the first and second power splitters for processing the reflector output and feedback signals.
