Fiber coupling efficiency in ocean with adaptive optics corrections
Journal of the Optical Society of America B, 2023Underwater optical wireless communication (UOWC) is a very promising technology that enables high-speed data transfer through the use of laser beams in an oceanic turbulent medium. The high-tech fiber optical devices, which are already available in the market, can be integrated with the UOWC systems.

We theoretically study the fiber-coupling efficiency of Gaussian–Schell model beams propagating through oceanic turbulence. The expression of the fiber-coupling efficiency is derived based on the spatial power spectrum of oceanic turbulence and the cross-

Effect of Waveguide Surface Roughness on the Fiber Coupling Efficiency of Inverse Tapers
Optical Fiber Communication Conference, 2015We investigate the effect of waveguide surface roughness on the coupling efficiency between silicon inverse tapers and lensed fibers. Short taper lengths of 30–50 micrometers are shown to achieve minimum coupling loss.

Cassegrain-Fiber-Coupling Efficiency through Atmospheric Turbulence
Asia Communications and Photonics Conference 2015, 2015Cassegrain-fiber-coupling expression is deducted under Kolomogorov power-law spectrum. The results show that with Cassegrain-shielding-ratio increases the coupling efficiency will decrease, but the impact will decease with the communication distance and turbulence intensity increase.

Fiber coupling efficiency for random light and its applications to lidar
Optics Letters, 1998Employing the van Cittert-Zernike theorem of classical coherence theory, we derive a general expression for the efficiency with which quasi-monochromatic random light can be coupled to an optical fiber by means of a lens. For the important case of a source with Gaussian intensity distribution, we obtain and discuss the dependence of the coupling ...

Fiber coupling efficiency for satellite and space to ground downlinks with pointing errors
Optik, 2020Abstract Fiber coupling efficiency is severely damaged by pointing errors and the atmospheric turbulence for satellite and space to ground downlinks. In this paper, correlated Beckmann distribution is derived from the transmitter to receiver in the context of downlinks.

Fiber coupling efficiency for free-space optical communication through atmospheric turbulence
SPIE Proceedings, 2004High-speed free-space optical communication systems have recently used fiber-optic components. The received laser beam in such a system must be coupled into a single-mode fiber at the input of the receiver module. However, propagation through atmospheric turbulence degrades the spatial coherence of a laser beam and limits the fiber-coupling efficiency.

Fiber coupling efficiency through turbulence medium for long and short exposures
2012 International Conference on Optoelectronics and Microelectronics, 2012Fiber-optic components have been used in high-speed free-space optical communication systems. The received laser beam in such a system must be coupled into a single-mode fiber at the input of the receiver module. However, laser propagation through atmospheric turbulence medium degrades pattern matching and limits the fiber-coupling efficiency.
