Highly uniform and efficient, broadband meta-beam-splitter/combiner
Saeed Hemayat, Liyi Hsu, Jeongho Ha +1
Subwavelength planar structured interfaces, also known as metasurfaces, are ultra-thin optical elements modulating the amplitude, phase, and polarization of incident light using na…
Broadband optical power limiter metalens
Liyi Hsu, Abdoulaye Ndao
In recent years, the need for high-power laser is of great interest for different applications ranging from direct-laser processing, light detection, medicine, and lighting. Howeve…
Efficient coupling between slanted bound states in the continuum cavity and plasmonic nanoantennas induced local field enhancement
Liyi Hsu, Fadi I. Baida, Abdoulaye Ndao
Over the last few years, optical nanoantennas are continuously attracting interest owing to their ability to efficiently confine, localize resonance, and significantly enhanced ele…
Topological lasers generating and multiplexing topological light
B. Bahari, L. -Y. Hsu, S. H. Pan +5
Vortices are topologically stable singularities at the center of a swirl of energy. Optical vortices are conventionally formed using diffractive optics or by bespoke optical elemen…
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…
Observation of plasmonic exceptional points
J. -H. Park, A. Ndao, W. Cai +5
Non-Hermitian singularities known as exceptional-points (EPs) have been shown to exhibit increased sensitivities but the observation of EPs has so far been limited to wavelength sc…
