Polarimetric surface plasmon resonance imaging biosensor [PDF]

Optics Letters, 2009
We report the realization of a polarimetric surface plasmon resonance imaging system capable of dynamically resolving a change in the optical anisotropy of biochemical films. Anisotropies as small as 10(-3) refractive index unit on nanometer-thick samples can be resolved.

Material Modification of Borofloat 33 During Scanning‐Based Microforming Using Femtosecond Laser Pulses

Advanced Optical Materials, EarlyView.
Possibilities for ablation‐free microforming of borosilicate glass using ultrashort laser pulses are presented. Depending on the laser parameters and scanning strategy, surface structures with profile heights of up to 20 µm could be produced. The work provides a comprehensive experimental and analytical characterization of the microforming process ...

Pseudo Quad-Pol Simulation From Compact Polarimetric SAR Data via a Complex-Valued Dual-Branch Convolutional Neural Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Compact polarimetry (CP) has attracted much attention in recent years due to its hybrid dual-polarization imaging mode. CP synthetic aperture radar has a larger swath and can provide more polarimetric information compared with the traditional dual ...

Synergistic Pyro‐Phototronics and Structural Anisotropy in CsAg2I3/GaN Heterostructures for High‐Performance Polarization‐Sensitive UV Photodetectors

Advanced Science, EarlyView.
The development of polarization‐sensitive ultraviolet photodetectors is limited by poor heterojunction quality and low polarization sensitivity. This study integrates synthesized CsAg2I3 single crystals with intrinsic non‐centrosymmetry into van der Waals heterojunction devices, demonstrating pronounced pyro‐phototronic effect.
