Chromatic Dispersion Manipulation Based on Metalenses

Advanced Materials, 2019
AbstractMetasurfaces are 2D metamaterials composed of subwavelength nanoantennas according to specific design. They have been utilized to precisely manipulate various parameters of light fields, such as phase, polarization, amplitude, etc., showing promising functionalities.

Na4B8O9F10: A Deep-Ultraviolet Transparent Nonlinear Optical Fluorooxoborate with Unexpected Short Phase-Matching Wavelength Induced by Optimized Chromatic Dispersion.

Angewandte Chemie, 2021
Exploring significant ultraviolet/deep-ultraviolet nonlinear optical (NLO) materials is hindered by rigorous and contradictory requirements, especially, possessing a moderate optical birefringence to meet phase-matching (PM).

Self-reference dispersion correction for chromatic confocal displacement measurement

, 2021
Dispersion is a very common phenomenon in the broadband optical systems. Chromatic confocal technology uses the chromatic aberration of lens to decode the axial displacement of the sample surface by the focus-wavelength of the reflected spectrum ...

Initial structure of dispersion objective for chromatic confocal sensor based on doublet lens

, 2021
Dispersion objective is the crucial device of chromatic confocal sensor (CCS). The dispersion range and numerical aperture (NA) determine the measurement range and the maximum measurement slope of CCS, respectively. In this paper, we present two kinds of
