Abstract :
The dynamic non-linear material response of graphene is introduced into finite-difference time-domain simulations using a carrier rate equation. Experimental measurements of grapheme´s relaxation time and saturation intensity are used to demonstrate sub-picosecond pulse formation via passive mode-locking in a 95 μm long Bragg cavity.
