Topological protection of partially coherent light [PDF]
Photonics Research, 2022 Topological physics exploits concepts from geometry and topology to implement systems capable of guiding waves in an unprecedented fashion. These ideas have led to the development of photonic topological insulators, which are optical systems whose eigenspectral topology allows the creation of light states that propagate along the edge of the system ...

Beam Properties of a Partially Coherent Beam Propagating Horizontally in Atmospheric Turbulence
Photonics, 2023 This study explored the impact of atmospheric turbulence on partially coherent light propagation. Atmospheric turbulence causes random modulation of the intensity and phase of light, resulting in a speckle pattern in the far field.

Propagation of partially coherent radiation using Wigner functions
Physical Review Accelerators and Beams, 2021 Undulator radiation from synchrotron light sources must be transported down a beam line from the source to the sample. A partially coherent photon beam may be represented in phase space using a Wigner function, and its transport may use some similar ...

A sub-wavelength Si LED integrated in a CMOS platform
Nature Communications, 2023 Integrated photonic systems require nanoscale on-chip light sources. Here Li et al., fabricate a silicon chip with LEDs smaller than the wavelength of light. This characteristic implies a partially coherent light emission, which allows the realization of
