Integrated structured light architectures [PDF]
Scientific Reports, 2021 AbstractThe structural versatility of light underpins an outstanding collection of optical phenomena where both geometrical and topological states of light can dictate how matter will respond or display. Light possesses multiple degrees of freedom such as amplitude, and linear, spin angular, and orbital angular momenta, but the ability to adaptively ...

Structured light scatteroscopy [PDF]
Journal of Biomedical Optics, 2014 A new imaging approach, structured light scatteroscopy (SLS), is demonstrated, which offers rapid wide-field imaging of microscopic morphological variations in bulk tissue surfaces. Elastic scattering of light offers exquisite sensitivity to ultrastructural changes at multiple size scales ranging from nanometers to millimeters, but in bulk tissues the ...

Kaleidoscopic structured light [PDF]
ACM Transactions on Graphics, 2021 Full surround 3D imaging for shape acquisition is essential for generating digital replicas of real-world objects. Surrounding an object we seek to scan with a kaleidoscope, that is, a configuration of multiple planar mirrors, produces an image of the object that encodes information from a combinatorially large number of virtual viewpoints.

Concealing with Structured Light [PDF]
Scientific Reports, 2014 While making objects less visible (or invisible) to a human eye or a radar has captured people's imagination for centuries, current attempts towards realization of this long-awaited functionality range from various stealth technologies to recently proposed cloaking devices. A majority of proposed approaches share a number of common deficiencies such as

Structured matter creates toroidal structured light
Light: Science & Applications, 2022 AbstractNano-structured metasurfaces have to be tailored from artificial atoms that act as toroidal emitters, giving rise to a new form of light long predicted: “flying doughnuts” as propagating spatial-temporal electromagnetic toroidal pulses in both the visible and THz regimes.

Metafiber transforming arbitrarily structured light
Nature Communications, 2023 AbstractStructured light has proven useful for numerous photonic applications. However, the current use of structured light in optical fiber science and technology is severely limited by mode mixing or by the lack of optical elements that can be integrated onto fiber end-faces for wavefront engineering, and hence generation of structured light is still

Spatial filtering of Structured Light [PDF]
Education and Training in Optics & Photonics Conference 2021, 2020 We present an approach to filter amplitude noise from arbitrary beam profiles. This work forms a tutorial on Fourier optics by enhancing the textbook case of Gaussian beams to more interesting cases of structured light.

Frequency conversion of structured light [PDF]
Scientific Reports, 2016 AbstractCoherent frequency conversion of structured light, i.e. the ability to manipulate the carrier frequency of a wave front without distorting its spatial phase and intensity profile, provides the opportunity for numerous novel applications in photonic technology and fundamental science. In particular, frequency conversion of spatial modes carrying
