Ligand-protected metal nanoclusters as low-loss, highly polarized emitters for optical waveguides

Science, 2023
Photoluminescent molecules and nanomaterials have potential applications as active waveguides, but such a use has often been limited by high optical losses and complex fabrication processes. We explored ligand-protected metal nanoclusters (LPMNCs), which

The waveguide invariant for a Pekeris waveguide

The Journal of the Acoustical Society of America, 2021
A closed-form waveguide invariant β for a Pekeris waveguide is derived. It is based on the modal Wentzel-Kramers-Brillouin (WKB) dispersion equation and implicit differentiation, in conjunction with the concept of the “effective boundary depth,” ΔH(θ), where θ is the propagation angle.

Plasmonic sensors based on Metal-insulator-metal waveguides for refractive index sensing applications: A brief review

, 2020
Optical sensors are widely used for refractive index measurement in biomedical, chemical, and food processing industries and offer high sensitivity to ambient refractive index variations due to the specific field distribution of the resonances.

Corner states of light in photonic waveguides

Nature Photonics, 2018
The recently established paradigm of higher-order topological states of matter has shown that not only edge and surface states1,2 but also states localized to corners, can have robust and exotic properties3–9.

Optical Waveguide Refractometers

2005
In this chapter we have illustrated a new method for the determination of the refractive index of liquid samples, based on Cerenkov second harmonic generation from suitable planar waveguides. The method allows the determination of the refractive index in the near infrared by detection in the visible.
