Patents by Inventor Henk Bulthuis

Henk Bulthuis 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).

  • Publication number: 20200326482
    Abstract: An optical coupler couples light from waveguides of a photonic integrated circuit (PIC) to output waveguides, for example waveguides of a planar lightwave circuit (PLC). The optical coupler includes optical elements having different optical properties. In some embodiments the optical properties vary to account for waveguide angled facets in the PIC, and in some embodiments the optical properties vary to account for the PIC being mounted at an angle compared to the PLC, or optical coupler.

  • Patent number: 10782472
    Abstract: A switch module includes a switch integrated circuit (IC), a photonic integrated circuit (PIC), and a planar lightwave circuit (PLC). The PIC may include a plurality of light sources, an optical splitter, and a plurality of modulators. A dual MEMS may be used to align lens arrays, which may be used to couple light from the PIC to the PLC.

  • Publication number: 20190361172
    Abstract: Light from discrete red, blue, and green lasers are combined into a single output using a planar lightwave circuit (PLC). In some embodiments some light from an output of the PLC is reflected back to the lasers, and in some embodiments the reflected light is primarily of one of the red, green, or blue wavelengths. In some embodiments multiple lasers of slightly differing wavelengths are provided as light sources for some or all of the red, blue, and green light.

  • Patent number: 10054739
    Abstract: An optical transceiver may include pairs of lasers, each laser of a particular pair generating light at the same wavelength and each pair of lasers generating light at different wavelengths. The light from the lasers may be demultiplexed onto a pair of outputs, with each output receiving light from different lasers of each pair of lasers.

  • Patent number: 9722706
    Abstract: A transmitter assembly incorporating multiple laser diodes that are wavelength multiplexed together using a planar lightwave circuit, and where the multiplexer's transmission spectrum depends on temperature at the same rate as the laser diodes. This allows a design for lower loss in the multiplexer and therefore is more power efficient.
