  • Publication number: 20220417729
    Abstract: User circuitry within a wireless User Equipment (“UE”) that may utilize multiple subscriber identity module (“SIM”) profiles activates two or more SIM profiles to be active simultaneously. The user circuitry transfers service requests for wireless data services using the SIM profiles to network circuitry. The wireless data services may have different slice service types over different operating frequency bands of different target cells. The network circuitry wirelessly exchanges data with wireless access nodes associated with the target cells over the operating frequency bands to establish packet data unit sessions comprising the slice service types using the respective SIM profiles such that multiple packet data unit sessions are active using multiple SIM profiles simultaneously. Various applications may be mapped to the appropriate SIM profile and packet data unit session based on the respective provisioned slice characteristics matching the respective application requirements.

  • Publication number: 20220393049
    Abstract: The present disclosure provides an integrated infrared circular polarization detector with a high extinction ratio and a design method thereof. The detector structurally includes a metal reflective layer, a bottom electrode layer, a quantum well layer, a top electrode layer, and a two-dimensional chiral metamaterial layer. Under circularly polarized light with the selected handedness, surface plasmon polariton waves are generated at the interface between the two-dimensional chiral metamaterial layer and the semiconductor, and has a main electric field component aligned with the absorption direction of the quantum wells, thereby enhancing the absorption of the quantum wells. Under circularly polarized light with the opposite handedness, since most of the optical power is reflected, surface plasmon polariton waves cannot be effectively excited, and the absorption of the quantum wells is extremely low, thus realizing the capability of infrared circular polarization detection with a high extinction ratio.
