    摘要： A coupling device for axially coupling together the ends of very thin optical fibres, fixed in one coupling house each, for achieving an optical connection between the fibres, and comprising a lens system arranged in each coupling house consisting a lens body, a glass body, a space for an optically means, and a fibre contact coaxially arranged thereto, shaped as a holder for at least one fibre. The focal point of the lens body is arranged to coincidence with the end surface of the fibre contact facing the lens body. The glass body is arranged to constitute a rear limit for the lens system, and is axially adjustable so that the focal point of the lens system, for the wavelength used, coincidences with the rear end surface of the lens system and the glass body, and thereby the end surface of the fibre contact facing the lens system.

    摘要： The present invention relates to an optical filter comprising an integrated wavelength dispersive element having an input for providing temperature compensation, particularly for providing passive temperature compensation in an arrayed waveguide grating. The present invention has found that by providing an arrayed waveguide grating having a thermally responsive pivotal input structure for changing an angle of a collimated input signal launched into a focusing lens, the input point can be selected in response to changing temperature in order to compensate for thermal drift of the center wavelength. Further, the present invention has found that by providing a reflective lens assembly for focusing an input signal at a selected input point of the input planar waveguide, alignment and tuning of an input and assembly can be improved and simplified. As an additional advantage, variable coupling parameters can be incorporated into a reflective coupling including input position, waveguide taper and planar waveguide length increment to provide relatively simple tuning in an integrated device.

    摘要： An optical fiber collimator having a lens (10), and an optical fiber chip (14) disposed at a distance from the lens, the optical fiber chip holding an end portion of an optical fiber (12) and having an end surface treated to be inclined. The optical axis of the optical fiber is made eccentric with respect to the center of the lens to set the eccentric quantity of the optical fiber so that the center of the lens substantially coincides with the center of a light beam incident on the lens. The kind of the lens is optional. The lens may be an inexpensive spherical lens or may be a gradient index rod lens. When a gradient index rod lens is used, a lens in which a surface facing to the optical fiber chip is treated to be inclined is used as the gradient index rod lens.

    摘要： An optical module which satisfies a required insertion loss and can be easily assembled with high productivity. The optical module includes first optical fiber, a first lens, an optical device, a second lens, and second optical fiber. The first lens receives an incident light from the first optical fiber and converts the incident light into a parallel light. The optical device receives the parallel light and performs predetermined optical processing on the parallel light. The second lens receives a transmitted parallel light from the optical device and converge the transmitted parallel light to produce an outgoing light. The second optical fiber receives the outgoing light. An optical axis of the first lens and an optical axis of the second lens are substantially coincident with each other. An optical axis of the first optical fiber and an optical axis of the second optical fiber are substantially parallel with each other and substantially parallel to the optical axes of the first and the second lenses.

    摘要： Collimating microlenses are “printed” from optical polymeric materials on the ends of optical fibers using ink-jet technology. In one embodiment the optical fibers are inserted into a collet, a stand-off distance from the open upper end of the collet. The open upper end is filled with optical fluid and a microlens is formed thereon to collimate light exiting the fiber through the microlens. In another embodiment optical fibers from a “ribbon” are separated and installed into a ferrule having multiple openings therethrough. In the same manner as in the collet embodiment, the ferrule openings serve as a mold for the lens formation with the end of the fiber being located at the focal distance of the lenslet formed in an on the ferrule. A non-wetting coating can serve to control spreading of the fluid optical material and allow lens radius control as well. The microlenses are hardened after formation.

    摘要： An optical fiber collimator array includes an optical fiber array block and a microlens array substrate. The optical fiber array block includes an angled surface and is configured to receive and retain a plurality of individual optical fibers, which carry optical signals. The microlens array substrate includes a plurality of microlenses integrated along a microlens surface and a sloped surface opposite the microlens surface. The microlens surface is coupled to the angled surface such that the optical signals from the individual optical fibers are each collimated by a different one of the integrated microlenses.
