Resonant second harmonic generation in random dielectric structures [PDF]
Journal of the European Optical Society-Rapid Publications, 2006 We show that resonant second harmonic generation can be obtained in random dielectric structures. The scheme is based on internal resonances due to the optical counterpart of Anderson localization.

Second-Harmonic Generation in Suspended AlGaAs Waveguides: A Comparative Study
Micromachines, 2020 Due to adjustable modal birefringence, suspended AlGaAs optical waveguides with submicron transverse sections can support phase-matched frequency mixing in the whole material transparency range, even close to the material bandgap, by tuning the width-to ...

Nonreciprocal second harmonic generation in a magnetoelectric material [PDF]
Science Advances, 2020 Nearly perfectly unidirectional second harmonic generation of light is realized in a magnetoelectric material. Mirror symmetries are of particular importance because they are connected to fundamental properties and conservation laws.

Second-harmonic generation in SiC polytypes [PDF]
Physical Review B, 1998 LMTO calculations are presented for the frequency dependent second harmonic generation (SHG) in the polytypes 2H, 4H, 6H, 15R and 3C of SiC. All independent tensor components are calculated. The spectral features and the ratios of the 333 to 311 tensorial components are studied as a function of the degree of hexagonality. The relationship to the linear
