Terahertz anomalous Hall effect in magnetic Weyl semimetal CoSnS
Ashutosh Singh, Hongjing Xu, Xielin Wang +6
Time-reversal-symmetry-broken Weyl semimetals are known to have at least two nodes in their electronic band structure, separated in momentum space and acting as sources and sinks o…
Efficient generation of entangled photons in the telecommunications range using nonlinear metasurfaces integrated with ScAlN/GaN heterostructures
Jaeyeon Yu, Jewel Mohajan, Mikhail Tokman +8
Entangled photons provide non-classical correlations that enable measurement sensitivities beyond classical limits, scalable fault-tolerant quantum computation, and fundamentally s…
Maximally efficient biphoton generation by single photon decay in nonlinear quantum photonic circuits
Mikhail Tokman, Jitendra Verma, Jacob Bohreer +1
We develop a general nonperturbative formalism and propose a specific scheme for maximally efficient generation of biphoton states by parametric decay of single photons. We show th…
Active mode locking of quantum cascade lasers operating in external ring cavity
D. G. Revin, M. Hemingway, Y. Wang +2
Stable ultrashort light pulses and frequency combs generated by mode-locked lasers have many important applications including high-resolution spectroscopy, fast chemical detection…
Midinfrared Third Harmonic Generation from Macroscopically Aligned Ultralong Single-Wall Carbon Nanotubes
D. T. Morris, C. L. Pint, R. S. Arvidson +5
We report the observation of strong third harmonic generation from a macroscopic array of aligned ultralong single-wall carbon nanotubes (SWCNTs) with intense midinfrared radiation…
Collective Antenna Effects in the Terahertz and Infrared Response of Highly Aligned Carbon Nanotube Arrays
L. Ren, Q. Zhang, C. L. Pint +8
We study macroscopically-aligned single-wall carbon nanotube arrays with uniform lengths via polarization-dependent terahertz and infrared transmission spectroscopy. Polarization a…
Generation of Superfluorescent Bursts from a Fully Tunable Semiconductor Magneto-plasma
G. T. Noe, J. -H. Kim, J. Lee +7
Quantum particles sometimes cooperate to develop a macroscopically ordered state with extraordinary properties. Superconductivity and Bose-Einstein condensation are examples of suc…
Giant optical nonlinearity of graphene in a strong magnetic field
Xianghan Yao, Alexey Belyanin
We present quantum-mechanical density-matrix formalism for calculating the nonlinear optical response of magnetized graphene, valid for arbitrarily strong magnetic and optical fiel…
Above-Bandgap Magneto-optical Kerr Effect in Ferromagnetic GaMnAs
C. Sun, J. Kono, Y. Cho +3
We have performed a systematic magneto-optical Kerr spectroscopy study of GaMnAs with varying Mn densities as a function of temperature, magnetic field, and photon energy. Unlike p…
Stable mode-locked pulses from mid-infrared semiconductor lasers
Christine Y. Wang, L. Kuznetsova, V. M. Gkortsas +13
We report the unequivocal demonstration of mid-infrared mode-locked pulses from a semiconductor laser. The train of short pulses was generated by actively modulating the current an…
Infrared generation in low-dimensional semiconductor heterostructures via quantum coherence
A. A. Belyanin, F. Capasso, V. V. Kocharovsky +2
A new scheme for infrared generation without population inversion between subbands in quantum-well and quantum-dot lasers is presented and documented by detailed calculations. The…
