The idea of adopting the space domain as the next frontier for optical communication has
received increasing attention in the last few years. Optical devices are the integral parts of a …

Scaling up cable capacity in a power-and cost-efficient manner is a goal of spatial-division
multiplexing (SDM) in long-haul optical communication systems. Integration is a key to …

Based on the intensity model of few-mode erbium-doped fiber amplifiers (FM-EDFAs), we
put forward a semi-analytic method for efficiently calculating the signal mode gains by …

Using the linear polarization (LP) mode decomposition method, we theoretically analyze the
beat effect between the same polarization components of the vector pump modes and …

The mode beating effects can be considered for improving the modeling accuracy of few-
mode erbium-doped fiber amplifiers (FM-EDFAs). A linearly polarized (LP) mode diversity …

An analytical method for few-mode erbium doped fiber amplifiers (EDFAs) is proposed by
introducing the uniformity coefficient of population inversion. The validity of the derivation …

In this paper, an O-band few-mode fiber amplifier is numerically simulated based on our
proposed few-mode bismuth-doped fiber. The different pump modes and powers, signal …

In order to reduce the loss of communication system based on orbital angular momentum
(OAM), an Er 3+-doped photonic crystal fiber (PCF) amplifier which can support amplification …

Long-haul optical fiber communication systems form the backbone of worldwide connectivity
in the 21 st century. In particular, submarine optical fiber cables today carry nearly 99% of all …

Les fibres multimodales ont longtemps été délaissées en raison des distorsions temporelles
et spatiales subies par la lumière au cours de sa propagation dans la fibre. Ces distorsions …
