High-harmonic generation from metasurfaces empowered by bound states in the continuum
George Zograf, Kirill Koshelev, Anastasia Zalogina +9
The concept of optical bound states in the continuum (BICs) underpins the existence of strongly localized waves embedded into the radiation spectrum that can enhance the electromag…
Low power, chip-based stimulated Brillouin scattering microwave photonic filter with ultrahigh selectivity
David Marpaung, Blair Morrison, Mattia Pagani +5
Highly selective and reconfigurable microwave filters are of great importance in radio-frequency signal processing. Microwave photonic (MWP) filters are of particular interest, as…
Atomically Thin Optical Lenses and Gratings
Jiong Yang, Zhu Wang, Fan Wang +8
Two-dimensional (2D) materials have emerged as promising candidates for miniaturized optoelectronic devices, due to their strong inelastic interactions with light. On the other han…
Narrow linewidth Brillouin laser based on chalcogenide photonic chip
Irina V. Kabakova, Ravi Pant, Duk-Yong Choi +4
We present the first demonstration of a narrow linewidth, waveguide-based Brillouin laser which is enabled by large Brillouin gain of a chalcogenide chip. The waveguides are equipp…
Local tuning of photonic crystal cavities using chalcogenide glasses
Andrei Faraon, Dirk Englund, Douglas Bulla +5
We demonstrate a method to locally change the refractive index in planar optical devices by photodarkening of a thin chalcogenide glass layer deposited on top of the device. The me…
Gallium transformation under femtosecond laser excitation: Phase coexistence and incomplete melting
O. P. Uteza, E. G. Gamaly, A. V. Rode +2
The reversible phase transition induced by femtosecond laser excitation of Gallium has been studied by measuring the dielectric function at 775 nm with ~ 200 fs temporal resolution…
Unconventional magnetism in all-carbon nanofoam
A. V. Rode, E. G. Gamaly, A. G. Christy +7
We report production of nanostructured carbon foam by a high-repetition-rate, high-power laser ablation of glassy carbon in Ar atmosphere. A combination of characterization techniq…
Ablation of solids by femtosecond lasers: ablation mechanism and ablation thresholds for metals and dielectrics
E. G. Gamaly, A. V. Rode, V. T. Tikhonchuk +1
The mechanism of ablation of solids by intense femtosecond laser pulses is described in an explicit analytical form. It is shown that at high intensities when the ionization of the…
