Abstract: Integrated optical waveguides, direct-bonded waveguide interface joints, optical routing and interconnects are provided. An example optical interconnect joins first and second optical conduits. A first direct oxide bond at room temperature joins outer claddings of the two optical conduits and a second direct bond joins the inner light-transmitting cores of the two conduits at an annealing temperature. The two low-temperature bonds allow photonics to coexist in an integrated circuit or microelectronics package without conventional high-temperatures detrimental to microelectronics. Direct-bonded square, rectangular, polygonal, and noncircular optical interfaces provide better matching with rectangular waveguides and better performance. Direct oxide-bonding processes can be applied to create running waveguides, photonic wires, and optical routing in an integrated circuit package or in chip-to-chip optical communications without need for conventional optical couplers.

Abstract: This application is directed to controlling an electrical idle state of a retimer of a data communication channel. A receiving side of the retimer obtains an input signal including at least an exit command and a data sequence following the exit command.

The retimer extends the exit command carried by the control signal, outputs the control signal carrying the extended exit command at an output of the retimer, and in accordance with a determination that the retimer has been equalized and locked, outputs the data signal carrying the data sequence at the output of the retimer.

Abstract: A video decoder is provided for the decoding of a video bitstream encoded in a temporal interpolated prediction (TIP) mode. First and second motion vectors pointing to respective reference frames, or reference pictures within those frames, are generated for a block of a current picture. The motion vectors are then refined by application of a decoder-side motion vector refinement (DMVR) process, based on a bilateral matching process, and the refined motion vectors are used to decode the block. The refinement may more specifically involve consideration of candidates for the refined motion vectors, selected by the bilateral matching. The refinement may be applied at both block and sub-block divisions of the current picture.
