Majorana Bound State Cavities
Babak Bahari, Jae-Hyuck Choi, Yuzhou G. N. Liu +1
Cavities play a fundamental role in optical physics by providing spatio-temporal confinement of energy that facilitates light-matter interactions. They are routinely utilized in a…
Room temperature electrically pumped topological insulator lasers
Jae-Hyuck Choi, William E. Hayenga, Yuzhou G. N. Liu +4
Topological insulator lasers (TILs) are a recently introduced family of lasing arrays in which phase locking is achieved through synthetic gauge fields. These single frequency ligh…
Nonlinear circular dichroism in Mie-resonant nanoparticle dimers
Kristina Frizyuk, Elizaveta Melik-Gaykazyan, Jae-Hyuck Choi +3
We study nonlinear response of a dimer composed of two identical Mie-resonant dielectric nanoparticles illuminated normally by a circularly polarized light. We develop a general th…
Engineering Interaction Dynamics in Active Resonant Photonic Structures
Yuzhou G. N. Liu, Omid Hemmatyar, Absar U. Hassan +4
The collective response of a system is profoundly shaped by the interaction dynamics between its constituent elements. In physics, tailoring these interactions can enable the obser…
Individual nanoantennas empowered by bound states in the continuum for nonlinear photonics
Kirill Koshelev, Sergey Kruk, Elizaveta Melik-Gaykazyan +4
Bound states in the continuum (BICs) represent localized modes with energies embedded in the continuous spectrum of radiating waves. BICs were discovered initially as a mathematica…
Enhanced second-harmonic generation with structured light in AlGaAs nanoparticles governed by magnetic response
Elizaveta V. Melik-Gaykazyan, Kirill L. Koshelev, Jae-Hyuck Choi +4
We employ structured light for the second-harmonic generation from subwavelength AlGaAs nanoparticles that support both electric and magnetic multipolar Mie resonances. The vectori…
