  • Microstructuring optical wave guide devices with femtosecond optical pulses
    Patent number: 8107782
    Abstract: The present invention is directed to the creation of optical waveguiding devices from standard optical fibers by the creation of zones of permanently altered refractive index characteristics therein. A high intensity femtosecond laser beam is focused at a predetermined target region in the fiber so as to soften the glass material at the target region. After aligning the focal region with the target region in the fiber there will be relative movement between the focal region and the fiber, which has the effect of sweeping the focal region across the fiber in a predetermined path, so as to create a secondary waveguide path. A portion of the light traveling along the core is removed from the core along the secondary waveguide path such that the device can be utilized as an attenuator, an optical tap, or a polarimeter.

  • Ejector apparatus and associated assembly method for pluggable transceivers
    Patent number: 8052335
    Abstract: The present disclosure relates to a novel ejector apparatus for pluggable transceivers, such as transceivers defined by multi-source agreements (MSAs) including SFP, SFP+, XFP, and the like. The ejector apparatus utilizes a shrouded design where the ejector apparatus encapsulates the top, sides, and bottom of a pluggable transceiver thereby allowing an operator to grasp any side of the ejector apparatus to actuate engagement prongs. In keeping with MSA guidelines, the ejector apparatus utilizes prongs to disengage a locking mechanism in order for the kick out springs to release the module. Advantageously, the ejector apparatus enables high density placement of corresponding transceivers, allows access from all sides of the transceiver for ejection, and allows cables to remain connected to the transceiver during ejection.
