The present disclosure relates to transmission lines, and is particularly concerned with coupling of electromagnetic waves between two transmission lines. A device and method are presented, which enable broadband non-reciprocal coupling of the electromagnetic waves between two asymmetric transmission lines. This is achieved by controlling individually a set of tunable impedance elements, which are distributed along at least one of the transmission lines, to generate a set of impedance modulations in the transmission line, and with each impedance modulation new tones in the electromagnetic waves propagating in the transmission line. Depending on the direction of propagation of the electromagnetic waves, the new tones may constructively or destructively interfere with modes of the other transmission line, leading to the non-reciprocal coupling.

The present disclosure relates to an isolator device, which is realized by employing non-reciprocal coupling of electromagnetic modes of a transmission line. A device and method are presented, which enable broadband isolation in a bandwidth of interest. This is achieved by controlling a multitude of controllable impedance elements, which are distributed along a transmission line, to generate a set of impedance modulations in the transmission line, and with the impedance modulations new tones in the electromagnetic waves propagating supported by a first subset of modes in the transmission line. Depending on the direction of propagation of the electromagnetic waves, the new tones may constructively or destructively interfere, respectively leading to or preventing parametric coupling from the first subset of modes to a second subset of modes of the transmission line.

The disclosure relates to an integrated photonic chip (10) for optical coupling. The photonic chip comprises a substrate (11), a spot size converter (12) formed on a frontside surface of the substrate (11), a mirror (13) formed on the frontside surface of the substrate, and a meta-lens (14) formed in or on a backside surface of the substrate (11). The spot size converter (12) enlarges a diameter of a light beam in the photonic chip (10) from a smaller mode size to a larger mode size. The mirror receives the larger mode size light beam (15a) from the spot size converter (12), and reflects the light beam at an angle into the substrate. The meta-lens collimates the light beam (15b) reflected by the mirror and expanded when passing through the substrate, and outputs the collimated light beam (15c) towards the optical device.

This disclosure relates to network communication, particularly, with flows comprising encrypted packets. The disclosure provides a source node for sending packets to a target node, and a middle node between the source and target node. The source and the middle node each determine a temporary key based on a master symmetric key, which is available at the source and the middle node. Further, they each determine a pseudo-random sequence based on the temporary key. The source node sends a sequence of packets towards the target node, each packet comprising one element of the pseudo-random sequence as identifier, and the sequence of packets comprising the elements of the pseudo-random sequence in order. The middle node receives a plurality of packets, and identifies the sequence of packets sent by the source node in the plurality of packets by comparing identifiers of the packets with elements of the pseudo-random sequence.
