Nonlinear distortion of intense THz beams

New Journal of Physics, 2015
Near- and far-field beam profiles were measured for THz pulses generated in LiNbO _3 by optical rectification of 200 fs pulses with a tilted pulse front.

Nonlinear optical rectification and electronic structure in asymmetric coupled quantum wires

Results in Physics, 2020
Asymmetric coupled quantum wires provide the possibility for realizing obvious nonlinear optical rectification due to breaking the inversion symmetry. Here, we investigated nonlinear optical rectification (NOR) and electronic states in asymmetric coupled

Dynamic 3D scene depth reconstruction via optical flow field rectification. [PDF]

PLoS ONE, 2012
In this paper, we propose a depth propagation scheme based on optical flow field rectification towards more accurate depth reconstruction. In depth reconstruction, the occlusions and low-textural regions easily result in optical flow field errors, which ...

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

The Study of Two-order Nonlinear Optical Properties in Semiparabolic Quantum Well

四川大学学报. 自然科学版, 2017
Studies aimed at understanding the nonlinear optical properties of GaAs/AlGaAs semiparabolic quantum well under applied electric have focused on optical rectification and second harmonic generation. These studies have taken two complimentary approaches: (

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

Advanced Materials, EarlyView.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Efficient Cherenkov-Type Optical-to-Terahertz Conversion of Femtosecond Oscillator Pulses

Photonics
We demonstrate experimentally that a recently proposed structure comprising a tens of microns thick layer of LiNbO3 sandwiched between two totally reflecting Si prisms can serve as an efficient Cherenkov-type optical-to-terahertz converter of femtosecond
