Magnetic-Optic Effect-Based Topological State: Realization and Application
Frontiers in Materials, 2022 The topological state in photonics was first realized based on the magnetic-optic (MO) effect and developed rapidly in recent years. This review summarizes various topological states.

Quantum Nonlinear Optics with a Germanium-Vacancy Color Center in a Nanoscale Diamond Waveguide. [PDF]
Physical Review Letters, 2016 We demonstrate a quantum nanophotonics platform based on germanium-vacancy (GeV) color centers in fiber-coupled diamond nanophotonic waveguides. We show that GeV optical transitions have a high quantum efficiency and are nearly lifetime broadened in such

Parasitic High Q-Factor Open-Box Modes With 3-D Printed Dielectric-Filled Metal Waveguides
IEEE Access, 2021 High Q-factor open-box mode resonances have been found in the microwave measurements of several 3-D printed dielectric-filled metal-pipe rectangular waveguides (MPRWGs).

New Journal of Physics, 2023 Abstract We provide a theoretical framework to mold time-modulated mechanical metamaterials with frequency conversion and wave-steering capabilities. To illustrate the concept, we initially focus on 1D lattices, whereby a sufficiently slow time-modulation of the stiffness is employed to convert the frequency content of impinging waves ...

Superradiance for Atoms Trapped along a Photonic Crystal Waveguide. [PDF]
Physical Review Letters, 2015 We report observations of superradiance for atoms trapped in the near field of a photonic crystal waveguide (PCW). By fabricating the PCW with a band edge near the D(1) transition of atomic cesium, strong interaction is achieved between trapped atoms and

Plasmonic waveguides cladded by hyperbolic metamaterials [PDF]
Optics Letters, Vol. 39, Issue 16, pp. 4663-4666 (2014), 2014 Strongly anisotropic media with hyperbolic dispersion can be used for claddings of plasmonic waveguides. In order to analyze the fundamental properties of such waveguides, we analytically study 1D waveguides arranged of a hyperbolic metamaterial (HMM) in a HMM-Insulator-HMM (HIH) structure.

Waveguide-Mode Sensors as Aptasensors
Sensors, 2012 Aptamers are artificial nucleic acid ligands that can be generated by in vitro selection through partition and amplification. Aptamers can be generated against a wide range of biomolecules through the formation of versatile stem-loop structures.
