A new method of measuring second-harmonic generation efficiency using powder crystals is demonstrated. The second-harmonic wave generated with the evanescent wave (SHEW) is phase-matched for every material. The efficiency of the second-harmonic generation can be estimated from the SHEW power, ...
Very high conversion efficiency of the Cerenkov second harmonic generation in a nonlinear optical waveguide is demonstrated through numerical optimization of waveguide refractive indices, waveguide thickness, or domain-inversed period. Based on coupled-mode theory and a local-no-pump-depletion approximation...
Second-harmonic generation is of paramount importance in several fields of science and technology, including frequency conversion, self-referencing of frequency combs, nonlinear spectroscopy and pulse characterization. Advanced functionalities are enabled by modulation of the harmonic generation efficiency, which...
Second-harmonic generation efficiency Starting from the coupled mode Eqs. (6) and (7), we now assume that only A0 is excited, i.e., we are driving the mode at ω0 and all other mode FH amplitudes are 0: $$\frac{{{\rm{d}}}{{{\rm{d}}}t}{A}_{0}=-\frac{{\kappa }_{A,...
We attribute this record high SHG efficiency to the greatly increased optical Q factors at both infrared and near-visible wavelengths compared to previous device platforms as well as a relatively high material χ(2) value obtained in this work.

The demonstrated efficient SHG at green light from a single silicon nanoparticle is two orders of magnitude higher than that from unstructured Si films. This efficiency is significantly higher than that of many plasmonic nanostructures and small silicon nanopart... 展开 ...
Second order polarization, χ(2) E2, has been suggested to be useful for a variety of purposes, including parametric effects, most notably frequency doubling, also referred to as second harmonic generation (SHG). Frequency doubling has attracted particular attention, since laser diodes are not read...
