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…
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…
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…
