摘要： The back reflection in photodiodes is caused by an abrupt index contrast between the input waveguide and the composite waveguide/light absorbing material. In order to improve the back reflection, it is proposed to introduce an angle between the waveguide and the leading edge of the light absorbing material. The angle will result in gradually changing the effective index between the index of the waveguide and the index of the composite section, and consequently lower the amount of light reflecting back.

摘要： A multiport free-space wavelength division multiplexing (“WDM”) device is capable of handling multiple optical signals carried in multiple wavelengths (“λn”) using a prism. The WDM device includes an input collimator, prism, and optical filter. The input collimator receives an optical beam containing multiple wavelengths λn traveling through free-space. The prism uses at least two (2) surfaces to generate a first optical beam which travels in opposite direction of the optical beam. The optical filter is situated at a predefined angle with respect to the interface surface of the prism for facilitating frequency separation as well as extracts a first wavelength (“λ1”) from λn to form a first light signal with λ1 and form a second optical beam with the remaining wavelengths of λn. A collimator is used to guide the first light signal to a port.

摘要： An optical component has first and second planar lightwave circuits. The first and second planar lightwave circuits are aligned and jointed such that the position of an i-th optical waveguide (where i is an integer greater than or equal to 1 and less than or equal to n) of the first planar lightwave circuit and that of an i-th optical waveguide of the second planar lightwave circuit are matched on a joint interface. An angle formed by the i-th optical waveguide of the first planar lightwave circuit and a normal of the interface is configured to vary in accordance with a value of i within a range satisfying the Snell's law.

摘要： Conventionally, there has been a problem that a structure in which optical signals outputting from a substrate facet in a PLC are optically coupled to a different bulk type optical device is so complicated that its assembly is laborious. There also has been a problem that a structure in which an output facet of a PLC is polished with an angle results in an increase in coupling loss in free space optics. With a lens bonded to an angled facet of a PLC, an optical circuit of the present invention achieves an optical coupling, with low loss, to a bulk-type optical device or another PLC with a simple structure. Moreover, a lens part and an optical fiber part are respectively bonded to different core apertures exposed on a single angled facet. Thereby, optical signals can be inputted to and outputted from the PLC through the single facet.

摘要： In a lens system, such as for use in optical rotary joints, obliquely tilted cavities are inserted in a light path between light-waveguides and lenses to be coupled thereto in order to compensate lateral displacements between the light waveguides and the lenses. The cavities are filled with an optical medium having a predetermined refractive index in order to achieve a parallel displacement of a light-ray path, so that the ray path passes centrally through the lenses.

摘要： An apparatus for providing multiple collimated light beams from optical fibers and the method for producing such beams. The apparatus includes first and second optical fibers that carry light of first and second wavelengths, respectively, a fixture that maintains the fibers in a fixed relationship to one another, and a collimating lens. Light from each of the first and second optical fibers diverges from a face of the fixture. The collimating lens produces first and second collimated light beams that are displaced relative to one another from the light leaving the face. The face of the fixture is positioned to correct for chromatic aberration in the lens.
