Intercore crosstalk of heterogeneous multicore fiber is investigated based on coupled-mode theory. Random twisting model is used for estimating the crosstalk. The crosstalk of two kinds of fibers: triangular lattice 30-core fiber with four kinds of c

Space-division multiplexing (SDM) has become a promising technology for optical communications to seek a sustainable increment in data capacity to keep up with the ever-increasing bandwidth demand. SDM could provide massive parallelization in additio

Intermodal nonlinear signal distortions in a graded-index three-mode fiber are experimentally investigated in a recirculating loop transmission over distances up to 684 km. Transmitting a 24.5 GBaud 16-quadrature-amplitude-modulated spatial super cha

Few-mode fiber design suitable for long-haul dense space division multiplexing (SDM) transmission is proposed, where the spatial density and the splicing characteristics of the fiber is optimized. We numerically investigate the impact of the number o

We experimentally investigate distributed Raman amplification in a graded-index three-mode fiber over more than 80 nm signal bandwidth. We measured gain of up to 6 dB with 0.3 dB mode-dependence when pumping only the highest-order modes.

We realized a four-core fiber with 125 μm-cladding and four-holes using a novel fabrication technique, namely the over-cladding bundled rods (OBR) method. Four air holes were successfully introduced by using the OBR method without the need for a dri

A two-beam interferometer (TBI) with a two-mode fiber (TMF) as a dispersive medium in one arm and air in the other provides evidence of interference related to the complex degree of coherence $$\gamma $$. A TMF with a low differential group delay (DG
