Title
(EN) RECEIVER AND SYSTEM FOR TRANSPORTING AND DEMODULATING COMPLEX OPTICAL SIGNALS
(FR) RÉCEPTEUR ET SYSTÈME DE TRANSPORT ET DE DÉMODULATION DE SIGNAUX OPTIQUES COMPLEXES
Abstract
(EN) An optical signal receiver includes a multimode waveguide for receiving a complex modulated optical signal, an optical resonator that receives the complex modulated optical signal from the multimode waveguide and converts the complex modulated optical signal to an intensity modulated signal, and a detector that is configured to convert the intensity modulated signal into an electrical signal, the electrical signal having an amplitude indicative of an intensity of the intensity modulated signal from the optical resonator, and that provides a detected signal.
(FR) Récepteur de signal optique comprenant un guide d'ondes multimode pour recevoir un signal optique modulé complexe, un résonateur optique qui reçoit le signal optique modulé complexe provenant du guide d'ondes multimode et convertit le signal optique modulé complexe en un signal modulé en intensité, et un détecteur qui est conçu pour convertir le signal modulé en intensité en un signal électrique, le signal électrique présentant une amplitude indiquant une intensité du signal modulé en intensité provenant du résonateur optique, et qui fournit un signal détecté.
