Title (EN) APPARATUS FOR FLIPPING THE POLARIZATION STATE OF AN OPTICAL PULSE BETWEEN A TRANSMITTER AND A RECEIVER IN QUANTUM KEY DISTRIBUTION AND METHOD THEREOF
(FR) APPAREIL POUR BASCULER L'ÉTAT DE POLARISATION D'UNE IMPULSION OPTIQUE ENTRE UN ÉMETTEUR ET UN RÉCEPTEUR DANS UNE CRYPTOGRAPHIE QUANTIQUE ET PROCÉDÉ ASSOCIÉ
Abstract: front page image
(EN)An apparatus for flipping the polarization state of an optical pulse between a transmitter and a receiver in a quantum key distribution system comprising: a passive non flipping component that preserves the polarization state of said optical pulse; a passive flipping component that rotates the polarization state of said optical pulse orthogonally; and an active optical switch that receives said optical pulse and sends said optical pulse to either the said passive non flipping component or the said passive flipping component whereby the said optical pulse upon entering said active optical switch is directed either towards the passive non flipping component where its polarization state is preserved or towards the passive flipping component where its polarization state is rotated orthogonally.
(FR)L'invention concerne un appareil pour basculer l'état de polarisation d'une impulsion optique entre un émetteur et un récepteur dans un système de cryptographie quantique comprenant : un composant non basculant passif qui conserve l'état de polarisation de ladite impulsion optique; un composant basculant passif qui fait pivoter l'état de polarisation de ladite impulsion optique de manière orthogonale; et un commutateur optique actif qui reçoit ladite impulsion optique et envoie ladite impulsion optique soit audit composant non basculant passif, soit audit composant basculant passif, ladite impulsion optique lors de l'entrée dans ledit commutateur optique actif étant dirigée soit vers le composant non basculant passif dans lequel son état de polarisation est conservé, soit vers le composant basculant passif dans lequel son état de polarisation est pivoté de manière orthogonale.
