This PhD dissertation investigates multi-aperture receiving techniques that use fiber optic devices for coherent beam combining in free-space optical communication systems, aiming to improve signal reception and mitigate the effects of atmospheric turbulence.
Summary
This PhD dissertation explores using multi-aperture receivers with fiber optic devices for coherent beam combining in free-space optical communication systems to overcome atmospheric turbulence and efficiently couple received light into single-mode fibers. The research proposes and experimentally validates several innovative coherent combining techniques based on fiber couplers and polarization beam combiners, addressing scenarios with varying numbers of input beams and aiming to improve the performance of FSO communication systems.
