Partially coherent Mathieu–Gauss beams [PDF]
Scientific ReportsWe present a theoretical study and experimental generation of Mathieu–Gauss beams in the partially coherent regime. By means of a rotating ground glass diffuser and a spatial light modulator, we demonstrate independent control over both the spatial ...

Experimental synthesis of partially coherent beam with controllable twist phase and measuring its orbital angular momentum [PDF]
Nanophotonics, 2021 Twist phase is a nontrivial second-order phase that only exists in a partially coherent beam. Such twist phase endows the partially coherent beam with orbital angular momentum (OAM) and has unique applications such as in super-resolution imaging. However,

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.

Holographic beam shaping of partially coherent light [PDF]
Optics Letters, 2022 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 ...

Coupling Efficiency of a Partially Coherent Radially Polarized Vortex Beam into a Single-Mode Fiber
Applied Sciences, 2018 We study the problem of coupling partially coherent radially polarized (PCRP) vortex beams into a single-mode optical fiber. Using the well-known concept of the cross-spectral density (CSD) matrix, we derive a general expression for the coupling ...

Measurement of the coherence-orbital angular momentum matrix of a partially coherent beam.
Optics Letters, 2022 The recently introduced coherence-orbital angular momentum (COAM) matrix of a partially coherent beam [Phys. Rev. A103, 023529 (2021)10.1103/PhysRevA.103.023529] is experimentally measured for the first time, to the best of our knowledge.
