Holographic beam shaping of partially coherent light
We present an algorithmic approach for holographic shaping of partially coherent light, which is described by a mode expansion containing thousands of individual modes. Using gradient descent and algorithmic differentiation, our algorithm is able to find a set of axially separated phase patterns such that each mode undergoes an individually optimized ...

Unidirectional imaging with partially coherent light
Unidirectional imagers form images of input objects only in one direction, e.g., from field-of-view (FOV) A to FOV B, while blocking the image formation in the reverse direction, from FOV B to FOV A. Here, we report unidirectional imaging under spatially partially coherent light and demonstrate high-quality imaging only in the forward direction (A-> ...

Partially coherent UV–VIS light generation in photonic crystal fiber using femtosecond pulses
Light generated in optical fibers due to various nonlinear processes often has a broad spectrum and is commonly considered as a potentially convenient source of seed for tunable wavelength laser systems and many other applications.

Programmable on-chip synthesis and reconstruction of partially coherent two-mode optical fields [PDF]
Partially coherent light is typically studied in the context of freely propagating continuous fields. Recent developments have indicated the existence of a “coherence advantage” in multimode optical communications, where partially coherent light ...

Propagation of partially coherent radiation using Wigner functions
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 ...

Topological protection of partially coherent light [PDF]
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 ...
