Quantum emitter formation dynamics and probing of radiation induced atomic disorder in silicon
Wei Liu, Vsevolod Ivanov, Kaushalya Jhuria +9
Near infrared color centers in silicon are emerging candidates for on-chip integrated quantum emitters, optical access quantum memories and sensing. We access ensemble G color cent…
Effect of Localization on Photoluminescence and Zero-Field Splitting of Silicon Color Centers
Vsevolod Ivanov, Jacopo Simoni, Yeonghun Lee +10
The study of defect centers in silicon has been recently reinvigorated by their potential applications in optical quantum information processing. A number of silicon defect centers…
Defect engineering of silicon with ion pulses from laser acceleration
Walid Redjem, Ariel J. Amsellem, Frances I. Allen +27
Defect engineering is foundational to classical electronic device development and for emerging quantum devices. Here, we report on defect engineering of silicon single crystals wit…
Scalable single-mode Berkeley Surface Emitting Lasers
Rushin Contractor, Wanwoo Noh, Walid Redjem +1
The scaling of electromagnetic apertures is a long-standing question that has been investigated for at least six decades but has still not been resolved [1-5]. The size of single a…
Enhancement of optical forces at bound state in the continuum
Haoye Qin, Walid Redjem, Boubacar Kante
Light-actuated motors, vehicles, and even space sails have drawn tremendous attention for basic science and applications in space, biomedical, and sensing domains. Optical bound st…
Active topological photonics
Yasutomo Ota, Kenta Takata, Tomoki Ozawa +6
Topological photonics has emerged as a novel route to engineer the flow of light. Topologically-protected photonic edge modes, which are supported at the perimeters of topologicall…
Designing a broadband and linear polarization metasurface carpet cloak in the visible
L. Y. Hsu, A. Ndao, B. Kanté
In the past few years, carpet cloaking attracted interests because of its feasibility at optical frequencies and potential in stealth technologies. Metasurfaces have been proposed…
All-dielectric metasurface cylindrical lens
Jeongho Ha, Abdoulaye Ndao, Liyi Hsu +2
Conventional optical components have been proposed to realize high-quality line focusing with uniform intensity distribution such as cylindrical lenses, segmented wedge-arrays, or…
Towards Random Metasurface based Devices
Matthieu Dupré, Liyi Hsu, Boubacar Kanté
Metasurfaces are generally designed by placing scatterers in a periodic grid. We propose and discuss design rules for efficient random and functional metasurfaces with anisotropic…
Integrated and Steerable Vortex Lasers using Bound States in Continuum
B. Bahari, F. Vallini, T. Lepetit +5
Orbital angular momentum is a fundamental degree of freedom of light that manifests itself even at the single photon level. The coherent generation and beaming of structured light…
From parabolic-trough to metasurface-concentrator
LiYi Hsu, Matthieu Dupré, Abdoulaye Ndao +1
Metasurfaces are promising tools towards novel designs for flat optics applications. As such their quality and tolerance to fabrication imperfections need to be evaluated with spec…
Exceptional Points in three-dimensional Nanostructures
Ashok Kodigala, Thomas Lepetit, Boubacar Kanté
Exceptional points (EPs) are degeneracies in open wave systems where at least two energy levels and their corresponding eigenstates coalesce. We report evidence of the existence of…
Experimental demonstration of non-magnetic metamaterial cloak at microwave frequencies
Boubacar Kante, Dylan Germain, Andre de Lustrac
Metamaterials have paved the way to unprecedented control of the electromagnetic field1,2. The conjunction with space coordinate transformation has led to a novel "relativity inspi…
