Patents by Inventor Pei-Keng FU

Pei-Keng FU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9864146
    Abstract: An apparatus for handling a fiber-array to be attached with a silicon-photonics chip. The apparatus includes a bottom-plate having a first trench formed with two first branches connected to two first recessed regions at a first end and one second branch straight to a second end thereof and a second trench sharing the same second branch and having two third branches connected to two second recessed regions with an angle towards two sides outside the two first branches. The bottom-plate includes many female clip structures located at the first end, the second end, and the two sides. The apparatus includes a top-plate having corresponding male clip structures configured to lock with the female clip structures to at least have two shaped cavities at the first end for firmly holding fiber ferrules of the fiber-array substantially without lateral and axial motion while leaving excess lengths of fibers outside the second end.

  • Patent number: 8931966
    Abstract: An optical triplexer and/or optical line terminal (OLT) compatible with 1.25 and 10 Gb/s passive optical networks is disclosed. The triplexer/OLT includes an optical fiber, first and second laser diodes, a photodiode, and first and second lenses. A hemispherical lens may be at an end face of the photodiode or receiver subassembly housing. A first optical splitter is mounted between the first and second lenses, and a second optical splitter is mounted between the optical fiber and the second laser diode. The first lens and first laser diode, and the second lens and second laser diode share respective common linear optical axes. The present triplexer/OLT advantageously accords with an interface standard IEEE802.3av-2009 PRX30. In addition, the present triplexer can advantageously implement analog receiving and digital transceiving, save optical fiber resources, and provide high efficiency coupling. Thus, requirements for high power output and smaller housing outlines can be served.
