Seta‐Inspired Mechano‐Intelligent Janus Bandage with Coordinated Adhesion–Contraction for Minimizing Scarring

Advanced Materials, EarlyView.
We developed a bioinspired mechano‐intelligent Janus bandage (MIB) with a hydrophobic flat exterior and a hydrophilic interior featuring gecko‐mimicking wedged microstructures, fabricated via micromolding and anisotropic plasma treatment. The MIB dynamically synchronizes adhesion and contraction, enabling precise force modulation.

Polarization conversion in the caviton driven by linearly polarized lasers

Physical Review E, 2022
In one-dimensional particle-in-cell simulations of a plasma irradiated by linearly polarized lasers from both sides of boundaries, it is found that there is an appreciable growth of the electromagnetic field in cavitons in the transverse direction perpendicular to the direction of polarization, which indicates the polarization conversion of the ...

Polarization conversion in confocal microscopy with radially polarized illumination

Optics Letters, 2009
The effects of using radially polarized illumination in a confocal microscope are discussed, and the introduction of a polarization mode converter into the detection optics of the microscope is proposed. We find that with such a configuration, bright-field imaging can be performed without losing the resolution advantage of radially polarized ...

Polarization Conversion in MoS2 Flakes

Semiconductors, 2020
We have studied experimentally a series of samples of layered MoS2 flakes with thicknesses varying from 1 to 10 μm and observed their strong in-plane optical anisotropy, which we attribute to the effects of strain in combination with fluctuations in the direction of the C-axis.

Polarization conversion from diffraction gratings

Physical Review B, 1991
If a surface-modulated diffraction grating is arranged so that the scattering vector does not lie in the plane of incidence of the illuminating radiation, then polarization conversion can occur. This conversion can be strongly enhanced if a surface mode, such as a surface-plasmon-polariton or guided mode, is excited at the grating surface.

Efficient and monolithic polarization conversion system based on a polarization grating

Applied Optics, 2012
We introduce a new polarization conversion system (PCS) based on a liquid-crystal polarization grating (PG) and louvered wave plate. A simple arrangement of these elements laminated between two microlens arrays results in a compact and monolithic element, with the ability to nearly completely convert unpolarized input into linearly polarized output ...

Polarization-Sensitive Photoelectric Conversion

Chemical Reviews
The photoelectric conversion process has traditionally been dominated by studies on light intensity, while the role of polarization remains an emerging and underexplored frontier. Despite the growing number of mechanisms and material architectures demonstrating polarization-sensitive photoelectric responses, a systematic framework to unify these ...

Polarization conversion in ring resonators

The 17th Annual Meeting of the IEEELasers and Electro-Optics Society, 2004. LEOS 2004., 2004
The effect of the polarization rotation in bent waveguide on the frequency response of optical ring resonators is theoretically and experimentally investigated. A simple model that fairly well agrees with measured spectral responses is proposed.
