20100259728 | OPTICAL COMBINER AND IMAGE PROJECTOR USING THE OPTICAL COMBINER - An optical combiner in which fewer parts are used comprises an optical component and a plastic body. The component comprises: a first filter reflecting first light having a first wavelength and being transparent to second light having a second wavelength and third light having a third wavelength; a second filter reflecting second light and being transparent to third light; and a base transparent to second light and third light. The first filter and the second filter are provided on opposed surfaces of the base. The plastic body has first, second, and third surfaces, and the first surface provides first, second, and third lenses. The component is provided in the plastic body such that light from the first lens is connected to a path to the second surface through the first filter and light from the second lens is connected to the path through the second filter. The third surface is a reflecting surface for connecting light from the third lens to the path. | 10-14-2010 |
20100259729 | OPTICAL COMBINER AND IMAGE PROJECTOR USING THE OPTICAL COMBINER - An optical combiner in which the number of parts used is lessened is made of a resin. The optical component comprises a first surface, a diffraction grating, and a second surface. The first surface is a surface providing first, second, and third lenses. The diffraction grating diffracts to a common optical path leading to the second surface light of the first wavelength incident on the first lens, light of the second wavelength incident on the second lens, and light of the third wavelength incident on the third lens. The second surface emits light incident thereon through the common optical path. The optical path from the first surface to the diffraction grating and the common optical path are constituted of the resin. | 10-14-2010 |

20120321253 | METHOD OF CONNECTING OPTICAL FIBER AND CONNECTING STRUCTURE OF OPTICAL FIBER - An optical fiber connecting method and optical fiber connecting structure which can efficiently connect a multicore fiber to a plurality of single-core fibers with high accuracy. The method comprises preparing an MT ferrule for holding an MCF, axially rotating and positioning the MCF with respect to the MT ferrule, and then fixing the MCF to the MT ferrule; preparing an MT ferrule for holding a plurality of SCFs, positioning them such that cores are arranged at respective positions corresponding to arrangements of a plurality of cores in the MCF, and then fixing the plurality of SCFs to the MT ferrule; and positioning and joining the MT ferrules such that the plurality of cores face the respective single cores, so as to connect the MCF to the plurality of SCFs. | 12-20-2012 |
20120328238 | OPTICAL DEVICE - An optical device which reduces coupling loss while improving practicality is provided. A multi-core fiber coupling device is an optical device which couples a multi-core fiber to single core fibers, and includes a first optical system which is located on optical axes of a plurality of beams emitted from the multi-core fiber, and which makes the optical axes of the respective beams non-parallel to each other, thereby making the beams in a state of being separated from each other, and a second optical system S | 12-27-2012 |
20120328244 | OPTICAL CONNECTOR, OPTICAL CONNECTING STRUCTURE AND METHOD OF MANUFACTURING OPTICAL CONNECTOR - An optical connecting member realizes an optical connecting between a multi-core fiber and a plurality of single-core fibers by a waveguide part which connects a first end face and a second end face. With the optical connecting member, a connected end which is connected to the first end face is a straight-line portion that is orthogonal to the first end face in each of the plurality of waveguide parts. In addition, a diverged end which is diverged to the second end face is a straight-line portion that is orthogonal to the second end face. Consequently, light that has passed through the waveguide parts is emitted from the first end face and the second end face substantially perpendicularly to the faces, thereby enabling optical connecting loss to be favorably inhibited. | 12-27-2012 |
20130223795 | OPTICAL COUPLING ELEMENT AND MANUFACTURING METHOD - The present invention relates to an optical coupling element to optically couple optical elements of different kinds to each other, which is provided with a plurality of cores. In the optical coupling element a first end and a second end opposed thereto are different in at least either of a core array and a core interval. The optical coupling element has a bent shape of at least a part of the optical coupling element itself including the cores, so that a light input/output direction at the first end is different from a light input/output direction at the second end. | 08-29-2013 |
