摘要： A 1½×2 optical switch has two GRIN lenses, each lens having two ports on its respective outward end face. The switch has a transmissive wedge-shaped switching element disposed between the GRIN lenses. When the switching element is disposed in the path between the GRIN lenses, a single connection is established between a port of the first GRIN lens and a port of the second GRIN lens, while light is prevented from coupling between the remaining ports.

摘要： There is described a method for fabricating an optical connector comprising: embedding each one of a plurality of first optical waveguides in a corresponding one of a plurality of first grooves of a first substrate; embedding each one of a plurality of second optical waveguides in a corresponding one of a plurality of second grooves of a second substrate; abutting the plurality of first optical waveguides and the plurality of second optical waveguides against walls of the plurality of first grooves and the plurality of second grooves, respectively, by securing a spacer plate between the first substrate and the second substrate so that the first optical waveguides and the second optical waveguides extend along a same axis, thereby obtaining an optical assembly having a front end substantially perpendicular to the axis; and beveling the front end of the optical assembly, thereby obtaining a beveled end for the first optical waveguides and a beveled end for the second optical waveguides offset along the axis for separately providing optical access by side coupling to the plurality of first optical waveguides and the plurality of second optical waveguides.

摘要： An optical device comprises a dispersion element, a reflector, and an angle-to-offset (ATO) element. The angle-to-offset (ATO) element has optical power. The dispersion element is positioned in or near a focal plane of the ATO element and adapted to separate an input wavelength division multiplexed (WDM) light beam received from an input port of the optical device into two or more channel light beams. The reflector is positioned in or near a focal plane of the ATO element and arranged to receive the channel light beams from the dispersion element via the ATO element. The reflector is designed to reflect at least one of the channel light beams toward a respective output port of the optical device. With this arrangement, the dispersion element, reflector and ATO element cooperate to optically demultiplex the input WDM light beam. Additional optical elements arranged in the propagation path between the reflector and the output port(s) and/or between the input port and the dispersion element can be used to provide further optical signal processing functionality such as dynamic channel equalization, add drop, or wavelength switching.

摘要： An optical switch is disclosed having 4-ports. The switch consists of a first GRIN lens having 2 ports adjacent its outwardly facing end face. A second GRIN lens is disposed to receive light from the first GRIN lens and has two ports adjacent its outer end face. In a first state, a first port from the first GRIN lens couples light with a first output port of the second GRIN lens. In a second state, a movable optical element in the form of a light transmissive wedge having a reflective surface, is disposed in the path between first and second GRIN lens, providing a connection between a port of the first GRIN lens and a second port of the second GRIN lens. In a third connect state, the reflective surface of the wedge connects a port of the first GRIN lens and an output port in the same first GRIN lens. Hence an N×M optical switch is disclosed.

摘要： A seal assembly especially suitable for use as the sealing element in the annular cylindrical bore of a concentric cylinder assembly. The seal assembly includes an annular insert structure of rigid material and an annular seal member of elastomeric material bonded to the insert structure. The annular insert structure has an I-beam cross-sectional configuration including an outer annular flange structure centered on an axis, an inner annular flange structure centered on the axis concentrically within the outer annular flange structure, and annular web structure extending radially between the inner and outer annular flange structures. The web structure coacts with the flange structures to define left and right continuous annular grooves in the left and right faces of the insert structure and defines a plurality of circumferentially spaced holes extending axially through the web structure between the left and right grooves. The annular elastomeric seal member fills the left and right grooves, fills the web structure holes, and extends to one side of the insert structure to form inner and outer annular sealing surfaces for coaction with the respective annular surfaces of the annular cylindrical bore.
