Light capturing within the defect located in linear one-dimensional photonic lattice [PDF]
Bulletin of Natural Sciences Research, 2021 Numerically investigated the light beam propagation through one-dimensional photonic lattice possessing one linear defect. It is shown how capturing of light depends on lattice characteristics as well as the width and wavelength of input light beam ...

Synchronization of light flash with the irradiation pulse in proton beam therapy: A case report
Technical Innovations & Patient Support in Radiation Oncology, 2023 The correlation between sensory light flash and proton beam delivery was evaluated by measuring the timing of pulse beam delivery and light flash sensing using an event recorder in an 83-year-old patient receiving proton beam therapy (PBT) for ...

Optical trapping with structured light: a review
Advanced Photonics, 2021 . Optical trapping describes the interaction between light and matter to manipulate micro-objects through momentum transfer. In the case of 3D trapping with a single beam, this is termed optical tweezers.

Particle-like topologies in light [PDF]
Nature Communications, 2021 Three-dimensional (3D) topological states resemble truly localised, particle-like objects in physical space. Among the richest such structures are 3D skyrmions and hopfions, that realise integer topological numbers in their configuration via homotopic ...

Demonstration of speckle resistance using space–time light sheets
Scientific Reports, 2022 The capacity of self-healing fields to reconstruct after passing through scattering media may prove useful in reducing speckle formation. Here, we study the speckle response of the space–time (ST) light sheet compared to a Gaussian wave packet, Airy beam,

Remote focusing of a light beam [PDF]
, 2015 The remote focusing of light in a graded-index medium via mode interference is demonstrated using exact analytical solutions of the wave equation. Strong focusing of a light beam occurs at extremely long distances and this repeats periodically with ...

Application of rotational accelerometers on the measurement of automotive headlamp cut-off deviation
European Mechanical Science, 2022 Automotive lighting products, such as Head Lamps (HL), Fog Lamps (FL), Daytime Running Lamps (DRL), face with mechanical vibrations during service life which may coincide with the resonance frequencies of the light source.

Surface related laser induced white emission of Cr:YAG ceramic
Scientific Reports, 2021 In this work we report the white light emission in transparent Cr:YAG ceramic pellet upon irradiation with focused beam of CW infrared laser diode. It was found that this phenomenon is specifically related to interaction of laser beam with a surface of ...

Wide beam steering by slow-light waveguide gratings and a prism lens
, 2020 A lattice-shifted photonic crystal waveguide (LSPCW) maintains slow light as a guided mode and works as an optical antenna when a kind of double periodicity is introduced.
