Microwaveguides Could Speed Control of Light Flux in PICs

Facebook Twitter LinkedIn Email
NIZHNY NOVGOROD, Russia, Jan. 2, 2019 — In order to increase the speed with which photonic integrated circuits (PICs) control light flux, researchers are investigating new materials with high optical nonlinearity. Among the promising materials are microwaveguides based on graphene, a material in which charge carrier concentrations can be effectively controlled using optical pumping or applied bias voltage. The work of a team from the Lobachevsky State University of Nizhny Novgorod—National Research University (UNN, also known as Lobachevsky University) could provide a new perspective on the dynamics of waves in nonstationary...Read full article
