“…Figure 1b shows an example of generation of up to seventh optical harmonic from an individual subwavelength AlGaAs resonator. [41] In this demonstration, the resonator was optically pumped with a mid-infrared light source, and optical harmonics were observed in the nearinfrared and the visible spectral ranges. The harmonic generation is enhanced by orders of magnitude at a resonance associated with bound states in the continuum.…”

Among the most prominent effects resulting from nonlinear light–matter interaction is the generation of correlated and entangled photons through various processes, notably via spontaneous parametric down‐conversion or spontaneous four‐wave mixing. Such nonlinear optical processes benefit from the concentration of electromagnetic fields in small volumes. Dielectric nanoresonators and their 2D layouts—metasurfaces—provide efficient ways to control light in subwavelength volumes enabling the enhancement of nonlinear light–matter interaction and the generation of entangled photons. Nanoresonators and metasurfaces offer a radical miniaturization of quantum light sources allowing better scalability, which opens a pathway toward arrangements of photon sources in complex subwavelength configurations for advanced photon state control. In this work, the recent progress in this emergent area of research is reviewed.

High‐index dielectric subwavelength structures and metasurfaces are capable of enhancing light‐matter interaction by orders of magnitude via geometry‐dependent optical resonances. This enhancement, however, comes with a fundamental limitation of a narrow spectral range of operation in the vicinity of one or few resonant frequencies. Here we tackle this limitation and introduce an innovative and practical approach to achieve spectrally tunable enhancement of light‐matter interaction with resonant metasurfaces. We design and fabricate resonance‐gradient metasurfaces with varying geometrical parameters that translate into resonant frequencies dependence on one of the coordinates of the metasurface. The metasurfaces are composed of bone‐like nanoresonators which are made of germanium, and they support high‐Q optical resonances in the mid‐IR spectral range. We apply this general concept to observe the resonant enhancement of the 3rd and 5th harmonics generated from the gradient metasurfaces being used in conjunction with a tunable excitation laser to provide a wide spectral coverage of resonantly‐enhanced tunable generation of multiple optical harmonics.This article is protected by copyright.

Optical modulation of high-harmonics generation in solids enables the detection of material properties, such as the band structure, and promising new applications, such as super-resolution imaging in semiconductors. Various recent studies have shown optical modulation of high-harmonics generation in solids, in particular, suppression of high-harmonics generation has been observed by synchronized or delayed multipulse sequences. Here we provide an overview of the underlying mechanisms attributed to this suppression and provide a perspective on the challenges and opportunities regarding these mechanisms. All-optical control of high-harmonic generation allows for femtosecond, and in the future possibly subfemtosecond, switching, which has numerous possible applications: These range from super-resolution microscopy to nanoscale controlled chemistry and highly tunable nonlinear light sources.

High-Harmonic Generation from Subwavelength Resonators

Abstract: We generate up to the 7th optical harmonic from a single AlGaAs resonator. The resonator hosts engineered modes associated with bound states in the continuum. We investigate both direct and cascade mechanisms of high harmonic generation.
