Phase Corrections With Adaptive Optics and Gerchberg-Saxton Iteration: A Comparison

open access: yesIEEE Access, 2019
Free space optical communications technique is the promising alternative for the access/fronthual networks to relieve the traffic congestion. The turbulence in the free space channel, however, could cause the phase distortions in optical signals, thus ...

OPTICAL TURBULENCE : CHAOS IN OPTICAL BISTABILITY

open access: yesLe Journal de Physique Colloques, 1983
The transmitted light from a bistable optical cavity can exhibit a variety of bifurcation phenomena, passing from a stationary state, through successive periodic and chaotic states to a final fully developed chaotic state, as the intensity of incident laser light is increased.
