Symmetry-driven Phononic Metamaterials
Simon Yves, Michel Fruchart, Romain Fleury +4
Phonons are quasiparticles associated with mechanical vibrations in materials. They are at the root of the propagation of sound and elastic waves, as well as of thermal phenomena,…
Passive harmonic mode-locked laser on lithium niobate integrated photonics
Yu Wang, Guanyu Han, Jan-Philipp Koester +8
Mode-locked lasers (MLLs) are essential for a wide range of photonic applications, such as frequency metrology, biological imaging, and high-bandwidth coherent communications. The…
High Numerical Aperture Achromatic Meta-Devices through Dispersion Compensation
Yuzhong Wang, Axiang Yu, Yayun Cheng +3
Dispersion engineering is a long-standing challenge in optical systems, and it is particularly important for metasurfaces, which naturally suffer from strong chromatic aberrations…
Extreme electrodynamics in time-varying media
M. Scalora, M. A. Vincenti, D. de Ceglia +7
Abrupt time variations of the properties of optical materials have been at the center of intense research efforts in recent years, with the prospect of enabling extreme wave transf…
Chiral exceptional point enhanced active tuning and nonreciprocity in micro-resonators
Hwaseob Lee, Lorry Chang, Ali Kecebas +6
Exceptional points (EPs) have been extensively explored in mechanical, acoustic, plasmonic, and photonic systems. However, little is known about the role of EPs in tailoring the dy…
