Modelling of terahertz wave pulse generation using photoconductive antennas

ORAL

Abstract

Graphene/Graphite (G), Black Phosphorus (BP), and Molybdenum disulfide (MOS2), three famous semiconductor materials, have been studied and investigated for potential use in THz photoconductive antennas (PCA) applications during this work. A Multiphysics numerical model based on COMSOL Multiphysics was introduced to study the coupling between the electrical and optical response of the PCAs. This model has allowed us to compute the photocurrent induced in each case by a 780 nm femtosecond pulse laser, then the waveform and spectral response were calculated. Physical and geometrical properties of the PCAs were tuned at each time to optimize the PCAs performance.
