Inkjet printed circuits with two-dimensional semiconductor inks for high-performance electronics
Tian Carey, Adrees Arbab, Luca Anzi +12
Air-stable semiconducting inks suitable for complementary logic are key to create low-power printed integrated circuits (ICs). High-performance printable electronic inks with two-d…
Terahertz frequency combs exploiting an on-chip solution processed graphene-quantum cascade laser coupled-cavity architecture
F. P. Mezzapesa, K. Garrasi, J. Schmidt +11
The ability to engineer quantum-cascade-lasers (QCLs) with ultrabroad gain spectra and with a full compensation of the group velocity dispersion, at Terahertz (THz) frequencies, is…
Microfluidization of graphite and formulation of graphene-based conductive inks
P. G. Karagiannidis, S. A. Hodge, L. Lombardi +12
We report the exfoliation of graphite in aqueous solutions under high shear rate [] turbulent flow conditions, with a 100\% exfoliation yield. The material is stabi…
Few-cycle pulses from a graphene mode-locked all-fiber laser
D. Purdie, D. Popa, V. J. Wittwer +6
We combine a graphene mode-locked oscillator with an external compressor and achieve~29fs pulses with~52mW average power. This is a simple, low-cost, and robust setup, entirely fib…
Wideband saturable absorption in few-layer molybdenum diselenide (MoSe2) for Q-switching Yb-, Er- and Tm-doped fiber lasers
R. I. Woodward, R. C. T. Howe, T. H. Runcorn +4
We fabricate a free-standing molybdenum diselenide (MoSe2) saturable absorber by embedding liquid-phase exfoliated few-layer MoSe2 flakes into a polymer film. The MoSe2-polymer com…
1.5 GHz Pulse Generation From a Monolithic Waveguide Laser With a Graphene-Film Saturable Output Coupler
R. Mary, S. J. Beecher, G. Brown +9
We fabricate a saturable absorber mirror by coating a graphene film on an output coupler mirror. This is then used to obtain Q-switched mode-locking from a diode pumped linear cavi…
2μm Solid-State Laser Mode-locked By Single-Layer Graphene
A. A. Lagatsky, Z. Sun, T. S. Kulmala +9
We report a 2μm ultrafast solid-state Tm:Lu2O3 laser, mode-locked by single-layer graphene, generating transform-limited~410fs pulses, with a spectral width~11.1nm at 2067nm. The m…
