  • Apparatus and method for transmitting optical signals through a single fiber optical network
    Patent number: 6839517
    Abstract: An apparatus for wavelength multiplexing optical signals, wherein the apparatus includes at least one optically conductive sleeve, at least one collimating lens positioned to receive a optical signal from the at least one sleeve, and at least one dichroic splitter positioned to receive the optical signal from the at least one collimating lens. A filter may further be positioned to receive the optical signal from the at least one dichroic splitter in order to further filter the optical signal. The apparatus for wavelength multiplexing is configured to provide optical isolation of at least 75 dB via the combination of the at least one dichroic splitter and filter elements.
    Type: Grant
    Filed: February 12, 2001
    Date of Patent: January 4, 2005
    Assignees: Agere Systems Inc., Triquint Technology Holding Co.

  • Fiber optic light diffuser
    Patent number: 5363458
    Abstract: Heat and light generating, fiber optic, cylindrical diffusers are structured to operate more efficiently and with increased uniformity by the inclusion of rings of prescribed indicies of refraction about the unclad distal end portion of the diffuser. Such a diffuser also includes a conical distal tip. A sealed Teflon (TM) sleeve containing diffusing material in place over the entire length of the diffuser also improves the uniformity of heat distribution.

  • Fiber optic cylindrical diffuser
    Patent number: 5337381
    Abstract: A fiber optic, cylindrical, light diffuser for medical use includes an unclad distal fiber end where the exposed core end has a conical shape. The core end is enclosed by a sleeve which contacts the clad portion of the fiber only and defines a closed chamber with the distal end of the fiber. The chamber is filled with light diffusing material. The diffuser exhibits highly uniform output light distribution and is capable of carrying relatively high power densities safely.
