  • Publication number: 20250102734
    Abstract: A semiconductor photonics device includes a plurality of grating couplers, each configured to couple a particular wavelength (or wavelength range) of an optical signal to a waveguide of the semiconductor photonics device. In some implementations, various implementations of optical signal splitters or filters described herein enable respective wavelengths (or respective wavelength ranges) to be passed to each of the grating couplers (while filtering out other wavelengths or other wavelength ranges), thereby enabling the grating couplers to each handle a respective wavelength (or respective wavelength range). This enables multiple wavelengths (or multiple wavelength ranges) to be distributed across multiple grating couplers, which may increase the bandwidth of the semiconductor photonics device relative to a semiconductor photonics device that includes only a single grating coupler.

  • Publication number: 20250048493
    Abstract: Techniques pertaining to power saving by data throughput pattern prediction in wireless communications are described. A user equipment (UE) determines whether a probability of a first value being greater than a second value is higher than a threshold. The UE triggers a radio resource control (RRC) connection release with a network responsive to the probability being higher than the threshold. The first value represents a succeeding continuous duration of no uplink (UL) and downlink (DL) data. The second value represents an RRC inactivity timer duration plus a threshold duration.
