Dense and Sharp Resonance Peaks in Stretched Moiré Waveguides
G. Alagappan, C. E. Png
In this article, we demonstrate dense resonant peaks in the transmission spectra of a rectangular waveguide inscribed with a stretched moiré pattern. We investigated an array of si…
Fabry-Perot Resonance of Bilayer Metasurfaces
G. Alagappan, F. J. Garcia-Vidal, C. E. Png
In this study, we constructed a Fabry-Perot cavity with nanostructured, thin resonant metasurfaces as meta-mirrors. We developed a temporal coupled-mode theory and provided an accu…
Tuning of Silicon Nitride Micro Cavities by Controlled Nanolayer Deposition
Dmitry A. Kalashnikov, Gandhi Alagappan, Ting Hu +4
Integration of single-photon emitters (SPEs) with resonant photonic structures is a promising approach for realizing compact and efficient single-photon sources for quantum communi…
Enhancing Optical Readout from Diamond AFM Tips for Quantum Nanosensing
Sumin Choi, Victor Leong, Gandhi Alagappan +1
Color centers in diamond are promising candidates for quantum nanosensing applications. The efficient collection of the optical signal is the key to achieving high sensitivity and…
