GATE-TUNABLE GRAPHENE-FERROELECTRIC HYBRID STRUCTURE FOR PHOTONICS AND PLASMONICS

摘要

The invention relates to a novel type of gate-tunable photonics and plasmonics which utilizes doped large-scale graphene coupled with ferroelectric material. The graphene-ferroelectric hybrid structure paves the way for the realization of ultra-fast, low power consumption and multi-wavelength operation saturable absorbers for applications in ultra-fast laser systems and novel types of plasmonics for applications in infrared detection, single-photon quantum devices and ultrasensitive detectors.
