Summary of "Microcavity Nonlinear Optics with an Organically Functionalized Surface."

We report enhanced optical nonlinear effects at the surface of an ultrahigh-Q silica microcavity functionalized by a thin layer of organic molecules. The maximal conversion efficiency of third harmonic generation reaches ∼1680%/W^{2} and an absolute efficiency of 0.0144% at pump power of ∼2.90  mW, which is approximately 4 orders of magnitude higher than that in a reported silica microcavity. Further analysis clarifies the elusive dependence of the third harmonic signal on the pump power in previous literature. Molecule-functionalized microcavities may find promising applications in high-efficiency broadband optical frequency conversion and offer potential in sensitive surface analysis.

Gallium indium phosphide microstructures with suppressed photoluminescence for applications in nonlinear optics.

Gallium indium phosphide (GaInP), lattice matched to gallium arsenide, shows remarkable second-order nonlinear properties, as well as strong photoluminescence (PL) due to its direct band gap. By measu...

Enhancement of femtosecond surface nonlinear optical signals with spatiotemporal focusing.

Nonlinear optical reflection spectroscopies for surface studies often suffer from their relatively weak signals. To enhance the signal strength, femtosecond input pulses are generally preferred, but t...

Terahertz radiation of microcavity dipolaritons.

We propose the use of dipolaritons-quantum well excitons with a large dipole moment, coupled to a planar microcavity-for generating terahertz (THz) radiation. This is achieved by exciting the system w...

Medical and Biotech [MESH] Definitions

Microscopic imaging techniques that utilize nonlinear responses of light-matter interactions which occur with high-intensity illumination, such as from LASERS, and specialized light signal detection instrumentation to produce images without the need for dyes or fluorescent labels.

The study of systems which respond disproportionately (nonlinearly) to initial conditions or perturbing stimuli. Nonlinear systems may exhibit "chaos" which is classically characterized as sensitive dependence on initial conditions. Chaotic systems, while distinguished from more ordered periodic systems, are not random. When their behavior over time is appropriately displayed (in "phase space"), constraints are evident which are described by "strange attractors". Phase space representations of chaotic systems, or strange attractors, usually reveal fractal (FRACTALS) self-similarity across time scales. Natural, including biological, systems often display nonlinear dynamics and chaos.
