Doppler-free selective reflection spectroscopy of electric-quadrupole transitions
Eng Aik Chan, Syed Abdullah Aljunid, Athanasios Laliotis +2
Electric-dipole-forbidden transitions play an important role as in quantum sensing, quantum information, and fundamental test in physics. As such, the development of novel and sens…
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…
Tailoring optical metamaterials to tune the atom-surface Casimir-Polder interaction
Eng Aik Chan, Syed Abdullah Aljunid, Giorgio Adamo +3
Metamaterials are fascinating tools that can structure not only surface plasmons and electromagnetic waves but also electromagnetic vacuum fluctuations. The possibility of shaping…
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…
