Génération et traitement du signal optique basés sur le filtrage linéaire de phase-seule dans les domaines temporel et spectral.

Dans cet article, on propose, en simulation, une méthode de génération optique d’ondes millimétriques sans filtre RF ni optique et sans polarisation DC utilisant, en

We first briefly revisit composite filters (adapted, phase-only, inverse, compromise optimal, segmented, minimum average correlation energy, optimal trade-off maximum

We report the demonstration of a THz device entirely fabricated with PCMs which can largely modify the transmission and polarization state of an incident THz wave using

A second family of continuous-wave modulation systems is angle modulation, which involves variation of the angle (instantaneous phase) of the carrier wave with

(a) Temporal intensity and phase profiles obtained after reconstruction based on our approach (solid curve) are compared with the measurements made with an APEX

More precisely, here an electro-optic modulator is used to imprint the initial temporal phase modulation, while a programmable and compact spectral phase shaper

Au cours de sa propagation dans une fibre optique hautement non-linéaire, cette modulation d’intensité va inscrire sur le signal à analyser, via la modulation de phase croisée
