摘要： A polarization beam combiner/splitter (“PBCS”) for combining and splitting multiple channels of light beams simultaneously is disclosed. The PBCS includes a first fiber array, a second fiber array, and an optical core composed of a birefringent or other suitable material. The first fiber array includes a plurality of optical fiber pairs, while the second fiber array includes a corresponding plurality of optical fibers. The optical core is sized to modify light beams from any of the optical fibers of the first or second array. In a beam combining operation, multiple channels of polarized beams are emitted by the optical fiber pairs of the first fiber array and passed through the optical core, which combines the beams into dual-polarized combined light beams. The combined beams exit the optical core and are received by the second array of optical fibers. A similar beam splitting operation can be performed on multiple combined beams.

摘要： A device functions as a polarization beam combiner and an isolator. When light is transmitted in a first propagation direction, a second beam is displaced towards a first beam. The second beam has a polarization orthogonal to the polarization of the first beam, and the second beam is substantially parallel to the first beam. The polarizations of the first and second beams are rotated by a same first amount in a first rotation direction and then rotated by the same first amount in a second opposite rotation direction. The first and second beams are combined by displacing the second beam towards the first beam. The combined beam is polarized along a first plane and second plane, which is orthogonal to the first plane. When light is transmitted in a second opposite propagation direction, the device is used to provide optical isolation.

摘要： A collimating device having adjustable features that facilitate proper optical alignment of components positioned within the collimator is disclosed. In one embodiment, the collimating device includes a collimating portion including a collimating element, a core portion containing an optical device, and at least one adapter portion. An engagement surface on one end of the collimating portion is shaped to engage a corresponding engagement surface on one end of the adapter portion to form an adjustment point. An additional adjustment point is defined between another end of the adapter portion and an end of the core portion. These adjustment points enable the collimating portion to be maneuvered with respect to the core portion in order to align the collimating device. Minimal clearances between the adjustment point surfaces minimize the amount of adhesive needed to bond the collimator portion together after alignment, thereby producing a more stable and secure collimating device.

摘要： A gain flattening and tap device. A gain flattening filter for use in fiber-optic communications includes a substrate. A GFF film is formed on a first surface of the substrate. An HR film is formed on a second surface of the substrate. The HR film is arranged to receive light from the GFF film and to reflect at least some of the light back through the GFF film. By passing the light through the GFF film multiple times, the effectiveness of the GFF film is multiplied. Further, by constructing the HR film to allow portions of the light to pass through, a tap may be implemented with the GFF.
