摘要： An optical waveguide amplifier is formed to include an adiabatic region disposed between an input single mode waveguide and a large area, multimode gain region. The utilization of the adiabatic region allows for a single mode signal to be supported and provides for a larger gain area to be formed, thus providing a larger gain and higher output power than conventional prior art waveguide amplifier arrangements.

摘要： In a pulsed Fabry-Perot laser, such as a Q-switched laser or a mode-locked laser, one of the resonator reflectors comprises a waveguide loop coupled to the gain medium via a circulator. In one embodiment, only a modulator is located in the loop. In another embodiment, the circulator is switchable and the loop may contain either an unidirectional device, such as an isolator, or may contain only the waveguide itself, depending on which states of the circulator are utilized in the switching process. Also described are several arrangements for multiplexing lasers of different operating wavelengths.

摘要： A fiber amplifier, such as a rare-earth doped fiber amplifier, includes at least two separate sections of (doped) fiber, where residual pump power remaining in one stage (for example, the output stage) of the amplifier is coupled into, and re-used by, the remaining section of (doped) fiber. In particular, a second, longer section of fiber is directly pumped by an externally supplied pump signal and a first, shorter section of doped fiber uses residual pump power from the second section as a pump signal input.

摘要： An optical fiber transmission link with reduced channel depletion due to stimulated Raman scattering is formed by including a high pass optical filter in the transmission fiber. The filter may comprise one or more discrete components, or may be formed as a “distributed” filter along the length of the optical fiber. The cut-off frequency for the high pass optical filter is selected to be immediately below the frequency of the input channel to be transmitted. When used in an arrangement with multiple input channels, the cut-off frequency is controlled to be immediately below the lowest input channel frequency.

摘要： In a laser such as a mode-locked or Q-switched laser, one of the resonator reflectors comprises a switchable Faraday rotator mirror coupled to a switchable magnetic field source. The operation of the laser is therefore controlled by the application of the magnetic field to the Faraday rotator device. When no magnetic field is applied, the device behaves as an isolator and thereby breaks the signal path between the resonator reflectors. When a saturation magnetic field is applied, the reflectors, disposed on opposite sides of the optical gain medium, thereby form a cavity such that lasing will occur. The device may be formed of discrete components or fabricated as an integrated optical device.
