通信装置
Document Type and Number:
Japanese Patent JP2004516697
Kind Code:
A
Abstract:
A optical communications apparatus has an optical transmitter (T) with a signal source (10) for supplying a data signal comprising data to be transmitted, a photo-emitter (40) for emitting photons, a spin injector (30) supplying spin-polarised charge carriers for causing the photo-emitter to emit photons having a polarisation determined by the spin-polarisation of te charge carriers supplied by the spin injector (30), and a controller (20) for controlling the spin injector to cause the spin polarisation of the charge carriers supplied by the spin polarisation of the charge carriers supplied by the spin injector (30) to be controlled in accordance with data to be transmitted such that, in operation, the photo-emitter (40) provides an optical signal in which the polarisation of the photons emitted by the photo-emitter is modulated on the basis of data supplied by the signal sources; and a receiver (R) with a polarisation of photons received from the photo-emitter (40) and a data extractor (24) for extracting data transmitted in the optical signal provided by the photo-emitter on the basis of the photon polarisations determined by the polarisation detector.
