  • Patent number: 12681290
    Abstract: In a variable optical attenuator (VOA) and a method of variably optically attenuating a light beam, a input lens receives an input light beam and an output lens outputs an output light beam. A mirror reflects the input light beam as the output light beam. The mirror or a moveable element is movable in a manner to block, pass, and/or reflect at least a portion of the light included in the input light beam and the output light beam, whereupon the output light beam has reduced or increased brightness or intensity versus the input light beam.
    Type: Grant
    Filed: January 4, 2024
    Date of Patent: July 14, 2026
    Assignee: II-VI Photonics, Inc.

  • Publication number: 20260003125
    Abstract: A wavelength division multiplexer (WDM) includes one or more lenses, a WDM filter, and multiple common, multiple reflected and multiple transmit optical fibers optically coupled to the one or more lenses. Light at a first wavelength propagates in either direction between one common optical fiber and one reflected optical fiber via the one or more lenses and the WDM filter, wherein the WDM filter reflects the light at a first wavelength during propagation in either direction between the common optical fiber and the reflected optical fiber. Light at a second wavelength propagates in either direction between the common optical fiber and one transmit optical fiber via the one or more lenses and the WDM filter, wherein the WDM filter passes the light at a second wavelength during propagation in either direction between the common optical fiber and the transmit optical fiber.
