Efficient two-photon excitation by photonic dimers

Optics Letters, 2019
In this Letter, we show that photonic dimers, the quantum mechanical bound states of two photons, enable efficient nonlinear two-photon excitation, primarily due to the Lorentzian energy anti-correlation and to the temporal proximity between the constituent photons.

Metallic nanoparticles-decorated NdxY1-xAl3(BO3)4 sub-micrometric particles to enhance anti-Stokes excitation performance

Optical Materials: X, 2023
In the anti-Stokes excitation of trivalent rare-earth ions (RE3+), the excitation photons energy is smaller than that of a given absorption transition, and the energy mismatch can be compensated by phonons annihilation from the host lattice.

Efficient unidirectional ridge excitation of surface plasmons

Optics Express, 2009
Using leakage-radiation microscopy, we characterize the efficiency of unidirectional surface-plasmon excitation with periodic (800 nm) arrays of 130-nm-high and 330-nm-wide gold ridges on a thin gold film illuminated with a focused (5-microm-wide) laser beam.

Efficiency improvement in the cantilever photothermal excitation method using a photothermal conversion layer

Beilstein Journal of Nanotechnology, 2016
Photothermal excitation is a cantilever excitation method that enables stable and accurate operation for dynamic-mode AFM measurements. However, the low excitation efficiency of the method has often limited its application in practical studies.

Motional effects on the efficiency of excitation transfer

New Journal of Physics, 2010
Energy transfer plays a vital role in many natural and technological processes. In this work, we study the effects of mechanical motion on the excitation transfer through a chain of interacting molecules with application to biological scenarios of transfer processes. Our investigation demonstrates that, for various types of mechanical oscillations, the
