“…This led to an inverse opal showing second harmonic generation (Figure b). These nonlinear optical inverse opals will be investigated further as the anomalous dispersion in such structures is believed to cause phase matching effects, which considerably boost the efficiency of nonlinear scattering effects. ,− …”

Three-dimensionally ordered macroporous materials have unique structural and optical properties, making them useful for numerous applications in catalysis, membrane science, and optics. Accessible and economic fabrication of these materials is essential to fully explore the many possibilities that these materials present. A new templating method to fabricate three-dimensionally ordered macroporous materials without overlayers is presented. The resulting structures are freestanding inverse opals with large-area uniformity. The versatility and power of our fabrication method is demonstrated by synthesizing inverse opals displaying fluorescence, chirality, upconversion, second harmonic generation, and third harmonic generation. This economical and versatile fabrication method will facilitate research on inverse opals in general and on linear and nonlinear optical effects in 3D photonic crystals specifically. The relative ease of synthesis and wide variety of resulting materials will help the characterization and improvement of existing anomalous dispersion effects in these structures, while providing a platform for the discovery and demonstration of novel effects.

“…The effect of the second harmonic generation looks unusual for a non-crystalline amorphous material of SiO 2 glob- ules. The reported observation of the effect is related to the situation of the opal matrix filled with immersion [7], and the mechanism is explained with account for the local breaking of the inversion symmetry at the surface of each spherical particle [8]. However, the nonlinear polarization at the second harmonic frequency can appear owing to the interference of an extremely high-power pulse with a seed radiation in the material [9].…”

We report the results of an experimental study of the temporal response of the artificial opal luminescence excited by UV pulses from a nitrogen laser at room temperature, liquid-nitrogen temperature, and in the intermediate range. While the response time does not exceed 15 ns at room temperature, the afterglow at liquid-nitrogen temperature was detected with a decay time of about 700 ms. We have revealed that the afterglow appears suddenly with just millisecondrange duration at a definite temperature of 130 ± 5 K. The temperature dependence of the afterglow is of importance for the explanation of surprising effects of the stimulated emission in a single nano-sized SiO2 globule and the second harmonic generation in the material at liquid-nitrogen temperature. K e y w o r d s: artificial opal, afterglow, nanocavity lasing.

“…Nonlinear diffraction was originally reported for second-harmonic generation (SHG) in systems with periodic spatial modulation of the quadratic susceptibility χ (2) . The nonlinear diffraction of SHG and third-harmonic generation (THG) was further demonstrated for various periodic systems including 2D − and 3D nonlinear photonic crystals. , In these systems, second or third harmonics were generated efficiently as the nonlinear Bragg law was fulfilled at the quasi-phase matching condition. Diffraction is also actively studied in metasurfaces, 2D arrays of subwavelength nanoresonators, which allow one to manipulate the phase, amplitude, and polarization of transmitted or reflected light by engineering the constituent elements (i.e., meta-atoms) .…”

Metasurfaces are versatile tools for manipulating light; however, they have received little attention as devices for the efficient control of nonlinearly diffracted light. Here, we demonstrate nonlinear wavefront control through third-harmonic generation (THG) beaming into diffraction orders with efficiency tuned by excitation of hybrid Mie–quasi-bound states in the continuum (BIC) modes in a silicon metasurface. Simultaneous excitation of the high-Q collective Mie-type modes and quasi-BIC modes leads to their hybridization and results in a local electric field redistribution. We probe the hybrid mode by measuring far-field patterns of THG and observe the strong switching between (0,–1) and (−1,0) THG diffraction orders from 1:6 for off-resonant excitation to 129:1 for the hybrid mode excitation, showing tremendous contrast in controlling the nonlinear diffraction patterns. Our results pave the way to the realization of metasurfaces for novel light sources, telecommunications, and quantum photonics.
