Nondegenerate Nonlinear Refraction In Semiconductors
Frontiers in Optics 2016, 2014 The dispersion of nondegenerate nonlinear refraction in semiconductors is measured using our beam-deflection method. With high nondegeneracy, n2 is significantly enhanced over the degenerate case, and rapidly switches sign to negative near the ...

All-optical control of second-harmonic generation in β-BaB2O4 via coherent, terahertz-driven acentric lattice displacement [PDF]
Nature CommunicationsDynamical control of the nonlinear optical properties of solids – with light itself – will be essential for future ultrafast photonic technologies. Previously, methods to modulate nonlinear processes including second-harmonic generation (SHG) have relied

Hybrid Nonlinear Metasurface Refractive Lens. [PDF]
Nano LettNonlinear metasurfaces have been extensively studied, offering new capabilities to generate and control light. Usually, nonlinear metasurfaces are fabricated on planar substrates where the entire functionality is encoded in the metasurface design. Here, we study a new route to nonlinear metasurface-based optics by coating linear refractive elements ...
