  • Patent number: 11977248
    Abstract: The present invention relates to an optical filter with nanostructured layers and spectral sensors with layers of such kind. The optical filter has at least two nanostructured layers, each of which forms a transmission grating from grating wires extending parallel to each other. The grating wires of the two transmission gratings intersect each other and are positioned one on top of the other in the optical filter. An optical polarise which polarises incident optical radiation linearly parallel to the grating wires of one of the two transmission gratings is arranged over the transmission gratings. The optical filter can be produced as a bandpass filter with standard semiconductor processes without additional layers or modification of said processes.

  • Patent number: 11979238
    Abstract: A user device, UE, for a wireless communication system is described. The wireless communication system includes a plurality of user devices, UEs. The UE communicates with one or more transmitting UEs using a sidelink, supports a certain number of HARQ processes, and buffers one or more transmissions for each HARQ process. During a unicast communication with a transmitting UE using the sidelink, the UE receives from the transmitting UE a transmission during a transmission time interval, the transmission associated to control data, e.g. SCI, including a HARQ process ID, buffers the received transmission for the HARQ process, and combines the buffered transmissions prior to decoding. In case a successfully identified transmission is not buffered, the UE indicates to the transmitting UE that the transmission is not buffered at the UE.

  • Publication number: 20240146013
    Abstract: A method and arrangement for compensation of thermally induced depolarising effects in an optical resonator employ a retroreflective prism effecting multiple instances of total internal reflection as one end mirror of the resonator. The retroreflective prism has a first roof edge face pair made of two perpendicular roof edge faces and at least one second face with total internal reflection or a second roof edge face pair. Laser radiation entering parallel to the optical axis of the resonator undergoes total internal reflection through an angle ? at the second face or the second roof edge face pair before it undergoes total internal reflection at the first roof edge face pair and emerges again from the retroreflective prism in a manner parallel to the optical axis of the resonator following another instance of total internal reflection at the second face or the second roof edge face pair.
