  • Patent number: 10747044
    Abstract: A sub-wavelength grating is placed inside a liquid crystal variable optical retarder to reduce polarization dependence of the optical retardation generated by the variable optical retarder. A small thickness of the sub-wavelength grating, as compared to a conventional waveplate, reduces the driving voltage penalty due to the in-cell placement of the sub-wavelength grating.

  • Patent number: 7813040
    Abstract: A double stage isolator is formed of face-to-face slabs or sheets of materials that will suitably split, combine, non-reciprocally rotate to ensure isolation in a reverse direction from output ports to respective input ports of any light launched into the input ports. A right angled Porro-prism is disposed at an end of the affixed together slabs having planar faces to direct light launched in a folded fashion to the output ports. A half waveplate is used in addition to beam splitter combiners and non-reciprocal rotators means that rotate the light by 90 degrees so as to pass a single beam in a forward propagating direction and to interchange the polarization of two sub-beams that pass through from an output port to an input port in a reverse direction.

  • Patent number: 7081996
    Abstract: An isolated polarization beam splitter or combiner, for joining light from different inputs into one common port, and for dividing a beam of light into orthogonal polarizations. In both modes of operation, the splitter/combiner provides isolation preventing transmission of light in a reverse direction. As a splitter, a beam of light is separated through a birefringent material into sub-beams of orthogonal polarization components, and each sub-beam is passed through a non-reciprocal polarization rotator to rotate the polarization so that a reflected beam, or other counter-transmitted light cannot return on the same path through the birefringent material to the source. As a combiner, two separate beams of light are launched with known orthogonal polarizations into a first birefringent material, passed through a non-reciprocal polarization rotator and then combined as orthogonal polarizations into a single output port.

  • Patent number: 6823093
    Abstract: 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.

  • Publication number: 20040184148
    Abstract: A multimode laser beam depolarization and combining architecture integrates a combiner for polarized multimode light beams with a multimode beam depolarizer, that produces a composite depolarized output beam optimized for application to a Raman optical amplifier. A high-order depolarizing 45° waveplate is used to effectively depolarize multimode laser beams produced by a Fabry-Perot (FP) laser. The high-order 45° waveplate has a length that achieves multi mode dispersion-dependent depolarization of the beam over its travel path through the crystal, and may comprise a birefringent material such as YVO4 having a large difference between its extraordinary and ordinary indices of refraction.

  • Publication number: 20040105039
    Abstract: The invention relates to a variable optical attenuator utilizing a variable polarization rotator, preferably in the form of a liquid crystal cell, positioned between two birefringent elements, preferably in the form of two similar birefringent crystals. The first birefringent element splits a beam light into orthogonally polarized sub-beams, which are passed through the liquid crystal cell, thereby undergoing a desired polarization rotation. The second birefringent element recombines only a portion of each of the first and second sub-beams providing the desired amount of light as an output beam. To minimize insertion loss, a first lens is positioned between the first birefringent element and the liquid crystal cell, and a second lens is positioned between the liquid crystal cell and the second birefringent crystal.
