Effects of residual coherence on the scintillation of a partially coherent beam

Optics Express, 2019
Recent results show that partially coherent beams (PCB) can be conveniently generated in a multimode fiber and modulated with data at gigabit per second rates, which makes them attractive for free-space optical communication through turbulent atmosphere. An important feature of these realistic beams in contrast to model ones is the presence of residual

Shaping partially coherent light by the coherent mode decomposition

Optics Express
The coherence properties of light are essential when it comes to its modulation, and light of partial coherence in particular demands special attention compared to fully coherent light. Designs for the latter have been favored by the compact platforms driving research into the manipulation of light at the microscale and below, such as photonic crystals,
