摘要： A waveguide optical amplifier package has a circulator and a planar waveguide amplifier optically communicating with the circulator. A core of the circulator receives an input beam, separates the input beam into a first beam and a second beam, and manipulates the first beam and the second beam so that they have the same polarization as they enter the waveguide. The waveguide includes one waveguide for each beam or a single waveguide that receives both beams. Following amplification of the beams power levels, the beams are directed into the circulator which combines the beams into an output beam that exits the circulator.

摘要： An optical device for demultiplexing an optical signal comprises a grating that receives an optical signal comprising a plurality of wavelength channels, and generates a plurality of spatially separated light beams. Each light beam is associated with a particular wavelength channel. The optical device further comprises an optical element that at least partially compensates a temperature based frequency shift associated with the spatially separated light beams. The optical device further comprises a plurality of lenses and a plurality of fibers. The plurality of lenses are arranged such that a spacing between at least a pair of lenses is determined to at least partially compensate a non-linearity introduced by the grating. Each fiber is associated with a corresponding lens and receives a corresponding light beam. At least one fiber is placed a distance that is less than a focal length associated with its corresponding lens.

摘要： A tunable PM fiber combiner is configured to be accurately alignable with and operative to combine into a single composite beam a pair of non-collimated, orthogonally polarized light beams transported over polarization maintaining (PM) optical fibers, whose mutual spatial separation may vary. The combiner includes birefringent elements, that are linearly or rotationally displaced to realize the composite beam. The resulting composite light beam may then be readily coupled (e.g. via a single mode fiber) to a downstream beam processing device, such as a Raman amplifier.

摘要： A unique reflective surface is employed to compensate polarization dependence of optical taps. Specifically, the reflective surface compensates optical tap induced polarization by employing the intrinsic properties of metals rather than complex thin film stacks. To this end, a reflective thin metal film or a polished reflective metal surface may be employed. In a particular embodiment of the invention, a reflective surface that is coated with a single dielectric thin film can also be employed. In one example, the metal is preferably tungsten because it exhibits a large difference in the spread of reflectance between the s and p polarization states.

摘要： A wavelength characteristic control device capable of variably controlling a wavelength characteristic in a satisfactory manner. A polarized light wavelength characteristic changing element has a wavelength characteristic such that the transmittances or reflectances of P- and S-polarized rays vary differently with respect to wavelength. Polarization variable control means subjects the plane of polarization of the polarized light incident on the polarized light wavelength characteristic changing element to rotatory control to change the ratio of the P-polarized ray to the S-polarized ray, thereby variably controlling the wavelength characteristic.

摘要： A method of filtering an input optical signal, the method including the step of: (a) utilising the phase response of a Gires-Tournois resonator to produce a corresponding spatial separation in a predetermined wavelength range of the input optical signal. The method further preferably can include the step of: (b) projecting substantially orthogonal beams onto the surface of a Gires-Tournois resonator at slightly different angles of incidence and utilising the phase difference in the phase response of the orthogonal beams to spatially separate the predetermined wavelength range. A birefringent wedge can be utilised to separate a polarised input beam into the substantially orthogonal beams for projection onto the surface of the Gires-Tournois resonator.

摘要： A system for generating a source of broadband light includes, in one embodiment, a plurality of light sources such as SLEDs or edge-emitting luminescent diodes (ELEDs) whose outputs are combined in at least one combiner unit. The combiner unit combines light from a plurality of light sources into a single mode output beam. In one embodiment, the single mode output beam is the input beam to an interferometer for optical coherence tomography. In another embodiment, a time-gain compensation (TGC) unit is in communication with the plurality of light sources. The TGC unit controls the plurality of light sources independently and simultaneously. In one embodiment, control of the plurality of light sources by the TGC unit is in synchrony with the variation in optical delay in the reference arm of the interferometer. The TGC unit may feature, for example, a modulated current regulator.

摘要： Systems and methods for modifying, switching, rearranging or otherwise controlling the individual wavelength components of DWDM optical signals are described, which employ compact refolding and reshaping of these dimensionally patterned beams within a confined volume. The wavelength components of the beam are diffractively dispersed with high diffraction efficiency, and then reversely converged to beam waists incident on different ones of an array of control elements such as liquid crystal cells, MEMs and other spatial light modulators, or fixed distributed patterns. With reflective control elements the wavelength components may be reversely refolded along reciprocal paths with rediffraction, to form a reconstituted and revised DWDM output signal. If the control elements transmit at least one of the wavelength components, a separate, adjacent three dimensional beam refolding path, with rediffraction, is used to feed recombined signals to a separate output. High diffraction efficiency and minimal optical aberrations are achieved by employing a diffraction grating and opposed Mangin mirror system as the principal elements for beam refolding. The approach is useful in systems servicing narrow channel separations, and in a wide variety of applications including channel equalization, interleaving, channel blocking, and channel grouping.
