Directional Emission From High-Q Asymmetric Hollow Whispering Gallery Resonators
Amal Jose, Ramgopal Madugani, Christophe Pin +1
Whispering gallery mode (WGM) resonators with broken rotational symmetry exhibit phenomena that are generally absent in conventional symmetric cavities, including directional emiss…
Spectral and spatial filtering of whispering gallery modes in precision-engineered microbubble resonators
Ramgopal Madugani, Amal Jose, Christophe Pin +3
Similar to microspheres, thin-walled microbubble resonators support whispering gallery modes (WGMs) that combine ultrahigh Q-factors and small effective mode volumes. In contrast,…
X-ray microcomputed tomography of 3D chaotic microcavities
Ke Tian, Mohammed Zia Jalaludeen, Yeon Ui Lee +2
Chaotic microcavities play a crucial role in several research areas, including the study of unidirectional microlasers, nonlinear optics, sensing, quantum chaos, and non-Hermitian…
Disruptive Forces in Metamaterial Tweezers for Trapping 20 nm Nanoparticles Based on Molecular Graphene Quantum Dots
Theodoros D. Bouloumis, Hao Zhao, Nikolaos Kokkinidis +4
In recent years, plasmonic optical tweezers have been used to trap nanoparticles and study interactions with their environment. An unavoidable challenge is the plasmonic heating du…
Unleashing Urease Protein Dynamics with Metamaterial Optical Tweezers
Domna G. Kotsifaki, Viet Giang Truong, Mirco Dindo +3
Investigating the dynamics of single biomolecules is essential for unlocking new frontiers in biophysics and medicine. Here, we present a transformative approach using metamaterial…
Roadmap for Optical Tweezers
Giovanni Volpe, Onofrio M. Maragò, Halina Rubinzstein-Dunlop +80
Optical tweezers are tools made of light that enable contactless pushing, trapping, and manipulation of objects ranging from atoms to space light sails. Since the pioneering work b…
