摘要： A feedback control circuit and method for controlling laser frequency employing an interferometric phase sensor which accepts a light output from a laser and combines a phase modulated version of the light output, with an unmodulated version. By modulating only one component of the signal in the interferometric sensor, the improved noise characteristics are obtained, while demodulation can be performed relatively easily and cheaply. Methods and enclosures for reducing ambient noise in an interferometer or the delay coil thereof are also described.

摘要： The invention relates to an article comprising a length of an optical fibre and a package, the optical fibre comprising a fibre Bragg grating dispersed over a FBG-section of the length of the optical fibre, the package comprising a carrier with a carrier surface for supporting at least a supported part of the optical fibre including the FBG-section. The invention further relates to an apparatus comprising the article, to its use and to a method of manufacturing such an article. The object of the present invention is to seek to provide an optimized (e.g. elongate) package having a relatively low sensitivity to mechanical vibrations from the environment. This is achieved by providing that the carrier surface for supporting the optical fibre comprising a fibre Bragg grating is convex in a longitudinal direction of the optical fibre during use of the article. This has the advantage of providing a lowering of the influence of vibrations from acoustic sources (or other sources of mechanical vibration) in the environment compared to prior art solutions. In an embodiment, the carrier comprises two different materials, each adapted to provide a specific tuning of the wavelength selected by the fibre Bragg grating. The invention may e.g. be used for the fibre lasers for sensing, (low frequency/low phase noise fibre lasers) in wavelength tuneable fibre lasers, and in packaging of fibre lasers in general.

摘要： An optical amplifier is provided including means for receiving a first optical input data signal. A first pump laser is provided for generating a first optical pump signal, and a first optical multiplexer is adapted to receive and combine the first optical input data signal and the first pump signal. The first optical multiplexer thus forms a first composite optical signal that includes the first pump signal and the first optical input data signal. The optical amplifier includes a first substrate having a first doped optical fiber adhered to or embedded within the substrate. The first multiplexer couples the first composite optical signal to an input end of the first doped optical fiber so that the first composite signal is transmitted through the first doped optical fiber. At the opposite end of the first doped optical fiber a first optical demultiplexer is positioned to receive the first composite signal after the first composite signal has been transmitted through the first doped optical fiber. The first demultiplexer removes the first pump signal from the first composite signal and produces a first optical output data signal having increased optical power relative to the first optical input data signal.

摘要： A method and apparatus for coupling substantial optical power into an optical fiber from the side without encumbering ends of the fiber. A special optical fiber, having a gain medium preferably including rare earth dopants in the core, is provided. One or more launch sections are selected at intervals along the special fiber with absorptive loops therebetween. The launch sections are stripped to their inner cladding layer, which preferably has a rectangular cross section, and positioned adjacent each other to form a launch region having a convex side mated to a launch port shaped to conform thereto, and with a low refraction index material contacting the corresponding concave side of the launch region. The concave side is preferably supported by an upwardly convex support block. Pump light is directed by appropriate optics into one or more faces of a launch port, which has a refractive index substantially matching that of the inner cladding layer into which it transmits the pump light. The pump light entering each face is preferably provided by one or more stripe diodes about as long as the total width of the adjacent launch sections in the launch region, and may include combined light from a plurality of sources. As the pump light travels along the special fiber in the absorptive loops between the launch sections, it is significantly absorbed by the gain medium of the optical fiber and thereby contributes optical energy to generate or amplify light in the core. The launch port faces may reflect unabsorbed light back into the special fiber, even while transmitting pump light at a different wavelength into the launch port.
