  • Publication number: 20180049212
    Abstract: Methods and systems for wireless packet switching include determining a schedule for a plurality of transceivers in an enclosure. The schedule specifies which of the plurality of transceivers will act as a transmitter and which will act as a receiver. Data is transmitted from each transmitter to a corresponding receiver with a configured beamforming direction. Data is transmitted from a transmitter to a corresponding receiver by a wired connection if an angle of the beamforming direction is lower than a minimum angle.

  • Publication number: 20150346431
    Abstract: Aspects of the invention are directed to a method for forming an optical waveguide structure. Initially, a base film stack is received with an optical waveguide feature covered by a lower dielectric layer. An etch stop feature is then formed on the lower dielectric layer, and an upper dielectric layer is formed over the etch stop feature. Subsequently, a trench is patterned in the upper dielectric layer and the etch stop feature at least in part by utilizing the etch stop feature as an etch stop. Lastly, a waveguide coupler feature is formed in the trench, at least a portion of the waveguide coupler feature having a refractive index higher than the lower dielectric layer and the upper dielectric layer. The waveguide coupler feature is positioned over at least a portion of the optical waveguide feature but is separated from the optical waveguide feature by a portion of the lower dielectric layer.
