Image reconstruction through a multimode fiber with a simple neural network architecture
Changyan Zhu, Eng Aik Chan, You Wang +5
Multimode fibers (MMFs) have the potential to carry complex images for endoscopy and related applications, but decoding the complex speckle patterns produced by mode-mixing and mod…
Optical Metrology of Sub-Wavelength Objects Enabled by Artificial Intelligence
Carolina Rendón-Barraza, Eng Aik Chan, Guanghui Yuan +3
Microscopes and various forms of interferometers have been used for decades in optical metrology of objects that are typically larger than the wavelength of light λ. However, metro…
Plasmono-Atomic Interactions on a Fiber Tip
Eng Aik Chan, Giorgio Adamo, Syed Abdullah Aljunid +3
Light-atom interaction can be engineered by interfacing atoms with various specially designed media and optical fibers are convenient platforms for realization of compact interface…
Large optical depth frequency modulation spectroscopy
Chang Chi Kwong, Eng Aik Chan, Syed Abdullah Aljunid +2
Band-resolved frequency modulation spectroscopy is a common method to measure weak signals of radiative ensembles. When the optical depth of the medium is large, the signal drops e…
Coupling of atomic quadrupole transitions with resonant surface plasmons
Eng Aik Chan, Syed Abdullah Aljunid, Giorgio Adamo +3
We report on the coupling of an electric quadrupole transition in atom with plasmonic excitation in a nanostructured metallic metamaterial. The quadrupole transition at 685 nm in t…
Doppler-free approach to optical pumping dynamics in the electric quadrupole transition of Cesium vapor
Eng Aik Chan, Syed Abdullah Aljunid, Nikolay I. Zheludev +2
The electric quadrupole transition is investigated in Cesium vapor at room temperature via nonlinear Doppler-free 6P-6S-5D three-level spectroscopy. Frequency-r…
