Journal ArticleDOI
Creation of cylindrical vector beams through highlyanisotropic scattering media with a single scalartransmission matrix calibration
TL;DR: In this paper , the authors presented a method to construct cylindrical vector (CV) beams through highly anisotropic scattering media (HASM) with only a single scalar transmission matrix (TM) calibration.
Journal ArticleDOI
Improving deep subwavelength imaging through terminal interface design of metallo-dielectric multilayered stacks
TL;DR: In this article, a symmetric metallo-dielectric multilayered stacks (MDMS) was investigated to improve the spatial resolution of subwavelength imaging operated in canalization regime.
Proceedings ArticleDOI

David P. Forrai,Darrel Endres,John W. Devitt,Andrew Sarangan,Qiwen Zhan,Aziz Mahfoud-Familia,Robert T. Mack,James S. Harris +7 more
TL;DR: Progress is described in developing focal plane array (FPA) technology that will address shortcomings in earlier devices and is focusing on placing micro-polarizing grids in very close proximity to the P-N junction of the detector.
Journal ArticleDOI
A fractionation strategy of cellulose, hemicellulose, and lignin from wheat straw via the biphasic pretreatment for biomass valorization
TL;DR: In this paper , an acid biphasic system with 2-methyltetrahydrofuran (2-MeTHF) organic solvent and dilute p-toluenesulfonic acid (p-TsOH) was employed for the simultaneous fractionation of three components.
Journal ArticleDOI
Vectorial sculpturing of spatiotemporal wavepackets
TL;DR: In this article , the authors introduced a quarter-wave plate in a pulse shaper using a two-dimensional spatial light modulator, and showed that wavepackets with much more sophisticated spatiotemporal vectorial structures such as spatio-temporal spin grating, spatio temporal spin lattice and spatio temporally twisting polarization can be generated, significantly expanding their ability in coherently controlling light matter interactions that may find broad applications.
