Few-mode fibers and coupled-core multi-core fibers are attractive transmission media for space-division multiplexed transmission systems as they enable a high spatial channel multiplicity whilst sustaining the current standard cladding diameter. This

We investigate recirculating transmission of a wideband S-, C- and L-band signal in a 4-core fiber. We transmit 552 x 25 GHz spaced, 24.5 GBd channels. covering more than a 120 nm bandwidth from 1487.8 nm to 1608.33 nm through each core of the multi-

Utilizing the additional transmission bandwidth of the S-band can add hundreds of WDM channels and lead to record fiber throughputs, but adoption lower wavelength bands may also allow MCFs with lower crosstalk and increased spatial density.

We investigate the impact of intercore crosstalk in a 7-core fiber on signal to noise ratio and achievable information rates for PDM-QPSK, PDM-16QAM, and PDM-64QAM formats. The achievable rate is reduced by 8%, 5.4% and 1.5%, at a crosstalk of −25.
Optical amplifiers are key elements in many types of optical systems including optical fiber communication links and laser-based radars. Some of the most important aspects of such amplifiers are their noise performance, optical bandwidth, and power e
