Abstract:
Second-order optical nonlinearities can be greatly enhanced by orders of magnitude in resonantly excited nanostructures. These resonant nonlinearities continually attract attention, particularly in newly discovered materials. However, they are frequently not as heightened as currently predicted, limiting their exploitation in nanostructured nonlinear optics. Here, we present a clear-cut theoretical and experimental demonstration that the second-order nonlinear susceptibility can vary by orders of magnitude as a result of giant destructive, as well as constructive, interference effects in compl

Abstract:
Third-harmonic generation (THG) and its origin are investigated in an anharmonic quantum well by the perturbation theory. The calculated results show that the nonlinear effect roots in an anharmonic oscillation of electrons deviate asymmetrically or symmetrically from an ideal harmonic oscillation, and the more the deviation is, the larger the nonlinearities will be. In addition, the nonlinear coefficient is also relative to the anharmonic-oscillation frequency in the model. The most important point is that the THG coefficient may be obtained over 10-10 (m/V)2, about ten orders of magnitude gr

Abstract:
AbstractNonlinear optical processes are vital for fields including telecommunications, signal processing, data storage, spectroscopy, sensing and imaging. As an independent research area, nonlinear optics began with the invention of the laser, because practical sources of intense light needed to generate optical nonlinearities were not previously available. However, the high power requirements of many nonlinear optical systems limit their use, especially in portable or medical applications, and so there is a push to develop new materials and resonant structures capable of producing nonlinear o

AbstractThin films containing small-sized quantum dots (QDs) and nanoparticles have shown strong optical nonlinearities caused by the confinement effect. Here, we report the study of third-order optical nonlinearities of silver sulfide (Ag2S) QD thin films using 800 and 400 nm, 30 fs pulses. The absorption spectrometry and transmission electron microscopy are used to characterize the synthesized 80 and 500 nm Ag2S QD films. The giant enhancement of nonlinearities is observed up to three to six orders of magnitude larger compared to those for the bulk and liquid Ag2S samples. We also demonstrat

It was demonstrated the simultaneous manifestation vibrations of nanotubes and diamond- like c-BN. The giant vibrational nonlinearity of BN nanostructures provides an effective nonlinear interaction of vibrational modes with the generation of high-frequency excitations. This fact finds its proof in observation of the glow in the bands of overtones and summary tones. When you are

Abstract:
Changes in absorption and refractive index caused by the absorption of laser light in CdS and GaSe ("dynamic” nonlinearities which may lead to optical bistability /OB/) were investigated. Nonlinear effects may be very strong ("giant" nonlinearities) due to the resonant enhancement near the sharp band edge in the case of resonant excitation of excitons or interband transition.
