Polypyrrole-Dopamine Nanofiber Light-Trapping Coating for Efficient Solar Vapor Generation.
ACS Applied Materials and Interfaces, 2021Solar vapor generation (SVG) typically uses a solar absorbing material at the water-air interface to convert solar energy into heat for evaporation. However, the intrinsic solar absorption of the material determines the upper limit of the solar energy ...

Light Trapping in Plasmonic Nanovessels
Advanced Optical Materials, 2017Inverse hollow nanocone arrays are fabricated by an efficient colloidal lithography technique and a facile transfer process. These structures have the peculiar features of nanobeakers, which may be promising reaction vessels. Local field distribution near this beaker and the influence on optical properties are investigated.

Light-baited suction traps are one of the most widely used tools for vector surveillance. Their popularity stems from ease of use even in remote locations, range and abundance of species caught, and low cost. The availability of smaller, portable models, like the CDC miniature light trap, have further increased their ubiquity in entomological field ...

American Scientist, 2008
Scientists are now exploiting orbital angular momentum in various experiments. Orbital angular momentum can arise if phase fronts, such as wave crests, become twisted around the direction of light propagation. Since the phenomenon was confirmed in 1992, researchers have investigated it in many experiments, initially with classical techniques but ...

Vortex revivals with trapped light
Optics Letters, 2001We predict that vortex dipoles nested in light beams trapped in graded-index media can undergo closed Berry trajectories, yielding periodic vortex annihilations and revivals along the light-propagation direction. The vortex revivals from vortex-free wave fronts are mediated by Freund stationary point bundles that carry the necessary Poincaré-Hopf ...

Trapping Light for Time of Flight
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018We propose a novel imaging method for near-complete, surround, 3D reconstruction of geometrically complex objects, in a single scan. The key idea is to augment a time-of-flight (ToF) based 3D sensor with a multi-mirror system, called a light-trap. The shape of the trap is chosen so that light rays entering it bounce multiple times inside the trap ...
