Nonlinear Optical Rectification in an Inversion-Symmetry-Broken Molecule near a Metallic Nanoparticle [PDF]
Nanomaterials, 2022 We study the nonlinear optical rectification of an inversion-symmetry-broken quantum system interacting with an optical field near a metallic nanoparticle, exemplified in a polar zinc–phthalocyanine molecule in proximity to a gold nanosphere.

Ionizing terahertz waves with 260 MV/cm from scalable optical rectification [PDF]
Light: Science & ApplicationsTerahertz (THz) waves, known as non-ionizing radiation owing to their low photon energies, can actually ionize atoms and molecules when a sufficiently large number of THz photons are concentrated in time and space.

Optical Ortho-Rectification for Image-Based Stream Surface Flow Observations Using a Ground Camera
Frontiers in Water, 2021 Image-based stream flow observation consists of three components: (i) image acquisition, (ii) ortho-rectification, and (iii) an image-based velocity estimation. Ortho-rectification is a type of coordinate transformation.

Optical rectification and electro-optic sampling in quartz
Optics Express, 2023 We report the electro-optic sampling (EOS) response and the terahertz (THz) optical rectification (OR) of the z-cut α-quartz. Due to its small effective second-order nonlinearity, large transparency window and hardness, freestanding thin quartz plates can faithfully measure the waveform of intense THz pulses with MV/cm electric-field strength.

Resonant optical rectification in bacteriorhodopsin [PDF]
Proceedings of the National Academy of Sciences, 2004 The relative role of retinal isomerization and microscopic polarization in the phototransduction process of bacteriorhodopsin is still an open question. It is known that both processes occur on an ultrafast time scale. The retinal trans→cis photoisomerization takes place on the time scale of a few hundred femtoseconds.

Optical rectification and field enhancement in a plasmonic nanogap [PDF]
Nature Nanotechnology, 2010 Metal nanostructures act as powerful optical antennas[1, 2] because collective modes of the electron fluid in the metal are excited when light strikes the surface of the nanostructure. These excitations, known as plasmons, can have evanescent electromagnetic fields that are orders of magnitude larger than the incident electromagnetic field. The largest
