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.

“…Several strategies have been posed to design high-Q optical microcavities, such as photonic crystal (PC) cavity [4][5][6][7], micropost (or micropillar) cavity [8,9] and microdisk (or microtoroid resonator) [10,11], which are frequently used to realize strong coupling in experiments. These systems provide test beds for quantum optics and quantum information science.…”

“…With the presence of a gain in the medium the lasing effect in such distributedfeedback structure can be achieved in so-called "edge modes" at both sides of a bandgap [4]. In general, the physics of light interaction with photonic crystals both in the frame of linear and nonlinear optics is quite rich of surprising effects like Anderson localization [5], Fano resonance [6], quantum optics phenomena [7,8] and nanoparticle plasmons [9]. Despite the main features related to the bandgaps in photonic crystals there are also specific moments originating from the structure of the constituent elements which build the photonic crystal.…”
