Multimode devices and components have attracted considerable attention in the last years,
and different research topics and themes have emerged very recently. The multimodality can …

Optical parametric amplifiers rely on second-order susceptibility (three-wave mixing) or third-
order susceptibility (four-wave mixing) in a nonlinear process where the energy of incoming …

We describe a scheme for generation of spatial-mode-entangled photon pairs in a few-mode
fiber and experimentally demonstrate generation of idler beams from classical seed signals …

Optical multicasting, which involves delivering an input signal to multiple different channels
simultaneously, is a key function to improve network performance. By exploiting individual …

In order to realize an optical cross-connect (OXC) converting wavelengths and spatial
modes into one-dimensional switching ports, we propose an active mode selective …

The realization of long-haul mode-division multiplexing (MDM) transmission requires a
matched optical amplifier with similar gain profiles among all guided modes. The fiber …

We present the design, fabrication, and characterization of a highly nonlinear few-mode fiber
(HNL-FMF) with an intermodal nonlinear coefficient of 2.8 (W· km)^− 1, which to the best of …

We proposed an amplification-enhanced measurement scheme of pump-dependent
dispersion in Erbium-doped fiber (EDF) based on optical low-coherence domain …

Multidimensional optical multicasting can increase the number of multicast optical channels
and enhance spectrum utilization, which is crucial for future high-capacity optical networks …

This paper proposes a physical layer security strategy of space division multiplex orthogonal
frequency division multiplexing system based on memristive neural network (MNN). Among …
