Patents by Inventor Jacob Sun

Jacob Sun 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: 8137572
    Abstract: A method of making a planar lightwave circuit (PLC) waveguide capable of being integrated with a surface-mounted component is presented. The method entails etching a silicon substrate to form a slanted wall, forming a nonreflective waveguide portion on the silicon substrate, and depositing a reflective layer on the slanted wall. Light travels through the nonreflective waveguide portion in substantially a first direction, and the light from the nonreflective waveguide portion strikes the reflective layer to be redirected in a second direction. The second direction may be the direction toward the surface-mounted component. A PLC waveguide device made with the above method is also presented.
    Type: Grant

  • Patent number: 7639908
    Abstract: The invention is a data transmission device that includes: an input Free Propagation Region (FPR) receiving a multi-wavelength signal and a single-wavelength signal, and two sets of arrayed waveguides coupled to the input FPR to carry the multi-wavelength signal and the single-wavelength signal, respectively. The arrayed waveguides demultiplex the multi-wavelength signal and create copies of the single-wavelength signal. The output plane of an output FPR receives the demultiplexed wavelengths and the copies of the single-wavelength signal such that one of the demultiplexed wavelengths and one of the copies of the single-wavelength signal focus onto the same position on the output plane. The device allows data (e.g., video stream) to be broadcast to all subscribers in a Wavelength-Division-Multiplexed Passive Optical Network (WDM-PON) architecture.
