摘要： A single-photon light source (2) comprises a photonic crystal structure the lattice of which extends in at least two dimensions and includes a crystal defect defining an optical waveguide (13) for guiding optical radiation emitted within the photonic crystal. An electric field generator (3) is operable to apply an electric field to the photonic crystal. A light emitter selected from: a quantum dot; a quantum well; a light-emitting diode (LED), is arranged within the photonic crystal for responding to the electric field to acquire an excited state and by decaying from the excited state thereby emitting optical radiation into the photonic crystal for guiding by the optical waveguide. The single-photon light source may be used as part of a quantum key distribution transmitter. An integrated single-photon detector (64) is disclosed as part of a quantum key distribution receiver.

摘要： A method of determining a unique identifier for a security element comprising: one or more optically readable structures in or on a body. The optically readable structures have an intrinsic band structure prior to application of a strain, which changes due to an applied strain. The method comprising: optically reading the security element to determine data indicative of an optical property of the security element when a strain is applied to the body via an external force. The unique identifier is determined from a map of the determined data with respect to the strain. The reading is undertaken for multiple locations across the security element when the strain is applied. The map is a map of the determined data across the security element with respect to the strain. The reading for multiple locations across the security element is undertaken in a single reading step, using a reader with a two-dimensional sensor.
