We experimentally evaluated the crosstalk impacts of cascaded ROADMs for SDM networks. Crosstalk induced Q penalties in 128 Gb/s transmission were compared for interleaved and grouped configurations, with 1–1.5 dB improvement for the interleaved setup.
We demonstrated 6.3-Tb/s (63 \(\times 128\) Gb/s) unrepeatered transmission over 402-km fiber link. This was achieved by employing a high-power Yb-free clad-pumped \(L\) -band erbium-doped fiber amplifier (EDFA) as a booster amplifier in the transmitter station, a combination of ultralarge-area fiber, low loss and zero-water-peak loss fibers, and a remote optically pumped amplifier (ROPA), which...
Higher order Bessel, Airy and Laguerre-Gaussian beams have recently been used to manipulate micrometer-sized objects in free space [1]. Here we use a coherent superposition of the two lowest order forward-propagating modes of a soft glass hollow-core photonic crystal fiber (HC-PCF, Fig. 1a) to control the axial and radial trapping position of particles inside the core. Because each fiber mode propagates...
In this paper we analyze the structural feature and electric field characteristic of the IDEs 1-3 mode piezoelectric fiber sensor. The constitutive equations and the finite element model of the IDEs 1-3 mode piezoelectric fiber sensor are also established. Moreover, we explore the effect of the key size of IDEs and the diameter of the piezoelectric fiber on performance of IDEs 1-3 mode piezoelectric...
