Title (EN) GRAPHENE MICROCAVITY FREQUENCY COMBS AND RELATED METHODS OF MANUFACTURING
(FR) PEIGNES DE FRÉQUENCE À MICROCAVITÉ DE GRAPHÈNE ET PROCÉDÉS DE FABRICATION ASSOCIÉS
Abstract:
(EN) Based on graphene heterostructure in chip-scale silicon nitride microresonators, optoelectronic control and modulation in frequency combs via group velocity dispersion modulation can be demonstrated. By tuning graphene Fermi level from 0.50 eV to 0.65 eV via electric-field gating, deterministic in-cavity group velocity dispersion control from anomalous (-62 fs2/mm) to normal (+9 fs2/mm) can be achieved with Q factor remaining high at 106. Consequently, both the primary comb lines and the full comb spectra can be controllable dynamically with the on/off switching of the Cherenkov radiation, the tuning of the primary comb lines from 2.3 THz to 7.2 THz, and the comb span control from zero comb lines to ~781 phase-locked comb lines, directly via the DC voltage.
(FR) Sur la base d'une hétérostructure de graphène dans des microrésonateurs en nitrure de silicium de la taille d'une puce, une commande et une modulation optoélectroniques dans des peignes de fréquence par modulation de dispersion de vitesse de groupe peuvent être mises en évidence. En accordant le niveau de Fermi du graphène de 0,50 eV à 0,65 eV par portillonnage à champ électrique, une commande déterministe de dispersion de vitesse de groupe dans la cavité entre une anomalie (-62 fs2/mm) et la normale (+9 fs2/mm) peut être obtenue avec un facteur Q restant élevé à 106. Par conséquent, à la fois les lignes de peigne primaire et les spectres de peigne complets peuvent être commandés de manière dynamique par la commutation sur marche/arrêt du rayonnement Cerenkov, l'accordage des lignes de peigne primaires de 2,3 THz à 7,2 THz, et la commande de la portée de peigne de lignes de peigne zéro à ~781 lignes de peigne verrouillées en phase, directement par l'intermédiaire de la tension continue.
