Abstract: The present invention relates to a polarization control apparatus. An embodiment of the present invention comprises a first and a second polarizing beam displacers, and a first and a second liquid crystal cells with both cells being responsive to external signals. The first polarizing beam displacer separates an input light beam into two substantially mutually orthogonal polarized light beams. Each of the two polarized light beams is rotated in polarization by at least one of the liquid crystal cells into a rotated polarized light beam. The second polarizing beam splitter combines substantially predetermined polarization components of the two rotated polarized light beams into an output light beam. Optionally, optically fiber collimators are disposed to provide the input light beam and receive the output light beam. The present invention may be adapted to multiple optical channel applications.

Abstract: This invention relates to a variable optical power splitter with an integrated variable optical attenuator. According to an embodiment of this invention, a first polarizing beam splitter separates an incident light beam into two substantially mutually orthogonally polarized light beams. Rotator cells are arranged to change the polarization directions of the polarized light beams to control the power splitting ratio between a first output and a second output. A second polarizing beam splitter diverts a first and a second predetermined polarization components in the polarized light beams to the first and the second outputs respectively. At each output, there are rotator cells and a polarizing beam splitter. These rotator cells changes the polarization directions of the diverted light beams to control the attenuations to the diverted light beams. The polarizing beam splitter combines predetermined polarization components of the diverted light beams into a single light beam at the output.

Abstract: A Virtually Imaged Phased Array (VIPA) contains a separate, precision-machined optical surface that forms one surface of the internal etalon and a boundary of the “radiation window,” in order to more easily achieve the optical-mechanical tolerances necessary for desired performance. VIPA design known to the prior art requires that a high reflective (mirror) optical coating be applied to a portion of a face of a plate of glass with a very sharp and well controlled boundary line across the surface while the remainder has an AR coating. This is difficult under the state of the art. In the disclosed VIPA, the required sharp boundary can be the machined physical edge of a plate of material (instead of the edge of a coating), which can be very precisely cut and controlled using common optical techniques. The disclosed VIPA is more easily manufactured than those known to the state of the art, and therefore is practical for applications such as the dispersing element in a chromatic dispersion compensator.
