  • Patent number: 10281661
    Abstract: This optical receptacle is provided with: an optical receptacle main body provided with a plurality of first optical surfaces and a plurality of second optical surfaces; and an optical filter. Light emitted from a photoelectric conversion element becomes incident on the first optical surfaces. The second optical surfaces allow light which becomes incident on the first optical surfaces, and passes through the inside, to exit towards an end surface of an optical transmission body. The optical filter is disposed so as to face some of the plurality of second optical surfaces, and attenuates the amount of light from the facing second optical surfaces. The optical filter is disposed with respect to at least one of the one or more second optical surfaces facing the optical filter, such that positional deviation between the first optical surfaces and the second optical surfaces is taken into consideration.

  • Patent number: 10254490
    Abstract: In an optical module including an optical axis adjustment mechanism, the reliability of fixation of a movable portion is enhanced while an adhesive is prevented from flowing out to an unintended portion. An optical module includes an element portion, a manipulation lever, a bank, a support spring, and a reservoir portion. The bank includes a lever-opposing portion having a step face facing a longitudinal side face of the manipulation lever. The support spring is connected at both ends to the element portion and the bank. The reservoir portion is surrounded in a bay shape, in a plan view, by the manipulation lever, the element portion, the support spring, and the bank and stores the adhesive fixing the lever to the substrate. The reservoir portion includes, in the vicinity of a handle of the manipulation lever, an outflow blocking portion blocking the outflow of the adhesive before curing.

  • Patent number: 10247890
    Abstract: A method of adjusting the parallelism of a surface of a block of optical fibers with a surface of a semiconductor chip or wafer laid on an XY table, including the steps of: a) providing a sensor rigidly attached to the XY table and a handling arm supporting the block, said surface facing the XY table; b) for each of three non-aligned points of the surface of the block, displacing with respect to each other the XY table and the block in the X and/or Y directions to place the sensor opposite the point, and estimating, with the sensor, the distance along the Z direction between the point and the sensor; and c) modifying the orientation of the block by means of the handling arm to provide the desired parallelism.

  • Patent number: 10215624
    Abstract: An integrated optical tap monitor takes the form of a highly-reflective outer coating disposed over the active region of an associated photodetector. The coating is of a material that allows for a majority of the impinging optical signal to be re-directed into an output path, while passing a small portion of the signal into the photodetector's active region for monitoring purposes. The integrated configuration is small enough to be housed within a standard TO can, and additional optical components (filters, attenuators, etc.) may be co-located with the integrated tap monitor. By virtue of incorporating the monitoring function with a reflective surface, the integrated tap monitor may be substituted for a turning mirror at any place along a signal path and provide the benefit of power monitoring while also performing signal re-direction.

  • Patent number: 10209453
    Abstract: A water-cooled package of an optical fiber head comprising a delivery optical fiber (DOF), a front optical end cap (OEC), a rear OEC, a glass ferrule, and a housing operates for delivering the laser light from DOF to free space. The rear OEC is fusion-spiced with a section of DOF with a cladding exposed whereas the section of DOF is enclosed in a bore of the glass ferrule. When the glass ferrule is connected and sealed between the front OEC and the rear OEC, cooling water in the water-cooled package is prevented from immersing the section of DOF to maintain reliability of DOF. It is, therefore, not needed to bond the section of DOF in a bore of the front OEC to be waterproof, minimizing varying stress-induced speckle patterns and ultimately maintaining beam quality of the laser light exiting from DOF to free space.
