Latest Patents

One of Yongbo Tang's latest patents is titled "Controlled tunneling waveguide integration (CTWI) for effective coupling between different components in a photonic chip." This invention describes an integrated photonics platform that comprises a plurality of at least three vertically-stacked waveguides. It enables light transfer from one waveguide of the photonic structure into another waveguide through a controlled tunneling method. The light power flows from the initial waveguide into the final waveguide while tunneling through the intermediate ones. The invention exemplifies a photonic integrated structure consisting of a laser guide as the upper waveguide, a passive guide as the middle waveguide, and a modulator guide as the lower waveguide. Controlled tunneling is facilitated by the overlapped lateral tapers formed on the same or different vertical waveguide levels. Further embodiments of this platform implement wavelength-(de)multiplexing, polarization-splitting, and beam-splitting functions.

Another notable patent is for an "Integrated coherent receiver having a geometric arrangement for improved device efficiency." This invention discloses a monolithically integrated coherent receiver chip with a geometric arrangement of on-chip components that significantly enhances the performance and manufacturability of a coherent receiver module for Dual Polarization Quadrature Phase Shift Keyed (DP-QPSK) applications and other optical coherent detection systems. The coherent receiver chip features two optical hybrids, three optical inputs, and eight electrical outputs. The optical hybrids are oriented perpendicular to the optical inputs and the electrical outputs, which are widely spaced and arranged in a co-linear fashion. This design simplifies module design and assembly while improving thermal management by separating the module's trans-impedance amplifiers.
