A solution-processed graphene-film coated on a fiber-based connector is used for stable, mode-locked femtosecond-duration pulses with 16mW average output power.
We use THz near-field microscopy with broadband THz pulses to image graphene nano-ribbons and to probe surface plasmon excitation and uniformity of graphene response. 3.3nm and 7nm thick graphene layers induce (∼10%) absorption from 0.5–2.5THz.
