Distributed characterization of bending-induced birefringence in spun fibers by means of P-OFDR

We report, for the first time, spatially-resolved measurements of bending-induced birefringence in ad hoc drawn single-mode spun fibers. The combined effect of spin rotation and bending birefringence is clearly highlighte

About the Differential Group Delay of Spooled Spun Fibers

We numerically and experimentaly analyze spooled spun fibers showing that spin and bending birefringence interact, originating peculiar PMD behavior. Actually, DGD of spooled spun fibers may be larger than that of the equivalent unspun fibers

Distributed characterization of bending effects on the birefringence of single-mode optical fibers

The effects of bending on randomly birefringent, single-mode optical fibers have been analyzed by means of polarization-sensitive optical frequency domain reflectometry. This distributed, pointwise characterization has been performed on ad hoc drawn spun fibers and on a ribbon cable. Experimental results are in agreement with the theoretical predictions and confirm the effectiveness of reflectometry as a means to characterize polarization properties of optical fibers.

Experimental evidence of independence between birefringence modulus and spin rate in periodically spun fibers

We report on polarization sensitive characterization of a set of various fibers, showing that in periodically spun fibers there is no evident correlation between the local birefringence strength and the applied spin rate

MIMO-less space division multiplexing transmission over 1 km elliptical core few mode fiber

We experimentally demonstrate 10-Gbit/s OOK MIMO-less SDM transmission over 1 km of a three-spatial-mode elliptical-core fiber at 1550 nm. Negligible power penalty is achieved thanks to the low modal crosstalk (<-22 dB) between any pair of the LP01, LP11a and LP11b modes

Elliptical core few mode fibers for multiple-input multiple output-free space division multiplexing transmission

We experimentally demonstrate space division multiplexed data transmission using the LP01, LP11a and LP11b modes over a 1 km length of elliptical-core few mode fiber (EC-FMF) at 1550 nm using 10 Gbit/s on-off keying data per spatial channel. Space division multiplexed transmission without the use of any multiple- input multiple output (MIMO) digital signal processing showed no power penalty relative to the single-mode or the back to back cases

Measurement of Temperature-Induced Polarization Drift and Correlation in a 7-Core Fiber

We study the correlation in polarization drift between different cores of a 7-core fiber subjected to temperature fluctuations. We present a method to quantify these changes and show that the drift in different cores is correlated to 98%

C- to L- band wavelength conversion enabled by parametric processes in a few mode fiber

We propose and experimentally demonstrate the potential for all-optical wavelength conversion within and between the C- and L-bands using inter-modal four-wave-mixing processes among different phase-matched and dispersion-tailored spatial modes in a single elliptical-core few mode fiber
