Coupling efficiency of a plane wave to few-mode fiber in the presence of beam random angular jitter
Journal of the Optical Society of America B: Optical Physics, 2021Using few-mode fiber to receive spatial light is an important method to obtain high coupling efficiency in long-distance free space optical communication systems. Here, we deal with the influence of random angular jitter on few-mode fiber coupling. First, the expression of mean-coupling efficiency from a spatial plane wave to few-mode fiber in the ...

Plane wave coupling into single-mode fiber in the presence of random angular jitter
Applied Optics, 2009Efficient coupling of coherent plane waves into single-mode fibers is a key technology for free-space optical communication at 1550 nm. Here we deal with the influence of random angular jitter on a plane wave to single-mode fiber coupling. The expression of mean-coupling efficiency in the presence of random jitter is handled in the pupil plane.

In an optically preamplified differential phase-shift keying (DPSK) receiver with Mach–Zehnder interferometer (MZI) demodulation, it is essential to couple free space light into a single-mode fiber, by which the received optical signal can be guided into the amplifier and MZI. Random angular jitter has a profound impact on fiber coupling efficiency, in

Extracting random jitter and sinusoidal jitter in ADC output with a single frequency test [PDF]
IEICE Electronics Express, 2015 An accurate and low-cost technique is proposed for sinusoidal jitter and random jitter estimation in high-speed ADC test. Exploiting the fact that clock jitter is modulated by the slope of input signal, the proposed method can simultaneously extract both
