Résumé: A new optical receiver scheme which combines wavelength conversion and homodyne detection is proposed and its performance is analysed by means of simulation. The main advantage of the proposed structure stems from the use of the same laser source for both, the wavelength conversion and the homodyne detection blocks, avoiding the use of any optical phase-locking loop. Results obtained show an improvement of the main performance parameters when compared with typical direct detection or homodyne receivers.
