Ultrafast saturable absorption dynamics in hybrid graphene/Si3N4 waveguides

Ultrafast saturable absorption dynamics in hybrid graphene/Si3N4 waveguides

We study the nonlinear optical properties of graphene integrated onto Si3N4 waveguides under picosecond and subpicosecond pulsed excitation at telecom wavelength. Saturable absorption of graphene under guided-mode excitation is measured, and the temporal effects related to the photoexcited carrier d...
