“…By infiltrating the opal globular PCs with liquids or solids, we could modify the optical and nonlinear properties of the system. 69,[77][78][79][80][81][82][83][84] We should note that the first PC model (Table I) is chosen to equal the empty opal PC, and second one represents the opal PC matrix infiltrated with nonlinear solid media with higher refractive indexes compared to the globules, e.g., NaNO 2 , LiNbO 3 or BaTiO 3 . It is expected that all the dependencies observed for these PC models could be generalized to the three-dimensional cases by adjusting the interaction between different states of the light polarization because the physical reason of the structural light focusing effect is linked with the curvature of particles and their periodic distribution inside the PC structure.…”

“…Examined model of the infiltrated PC is closely analogous to the opal PC infiltrated with different liquids and solids. 69,[77][78][79][80][81][82][83][84] Therefore, the condition of highly efficient PC pumping Eq. (8) could be used for the three-dimensional case, when it is adjusted for the interactions between the different polarization states.…”

A novel approach for the enhancement of nonlinear optical effects inside globular photonic crystals (PCs) is proposed and systematically studied via numerical simulations. The enhanced optical harmonic generation is associated with two- and three-dimensional PC pumping with the wavelength corresponding to different PC band-gaps. The interactions between light and the PC are numerically simulated using the finite-difference time-domain technique for solving the Maxwell's equations. Both empty and infiltrated two-dimensional PC structures are considered. A significant enhancement of harmonic generation is predicted owing to the highly efficient PC pumping based on the structural light focusing effect inside the PC structure. It is shown that a highly efficient harmonic generation could be attained for both the empty and infiltrated two- and three-dimensional PCs. We are demonstrating the ability for two times enhancement of the parametric decay efficiency, one order enhancement of the second harmonic generation, and two order enhancement of the third harmonic generation in PC structures in comparison to the nonlinear generations in appropriate homogenous media. Obviously, the nonlinear processes should be allowed by the molecular symmetry. The criteria of the nonlinear process efficiency are specified and calculated as a function of pumping wavelength position towards the PC globule diameter. Obtained criterion curves exhibit oscillating characteristics, which indicates that the highly efficient generation corresponds to the various PC band-gap pumping. The highest efficiency of nonlinear conversions could be reached for PC pumping with femtosecond optical pulses; thus, the local peak intensity would be maximized. Possible applications of the observed phenomenon are also discussed.
