Abstract

Conference Title: 2014 39th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz) Conference Start Date: 2014, Sept. 14 Conference End Date: 2014, Sept. 19 Conference Location: Tucson, AZ, USA We report nonlinear terahertz transmission through photoexcited graphene using optical-pump/terahertz-probe technique. Transient enhancement in the terahertz transmission of the graphene sample is observed when the sample is photoexcited. This transmission enhancement is found to decrease nonlinearly with the terahertz electric field.
