Abstract

A circular-birefringence highly nonlinear fiber (CB-HNLF) with the nonlinear coefficient of 12 /W/km is fabricated successfully by twisting a commercial silica-based highly nonlinear fiber. Using the cross-phase modulation in a 100-m-long CB-HNLF and subsequent optical filtering, we realize error-free pulsewidth-maintaining wavelength conversion of 160-Gb/s signal with only 0.7-dB polarization sensitivity. In addition to the simplicity and stability, the demonstrated scheme features an ultrafast repolarizing functionality, where the degree-of-polarization of the input signal is restored in an all-optical manner. These advantages make the scheme highly attractive to be employed in the future photonic networks.

Experimental setup of the 160-Gb/s polarization-insensitive WC. MZ: Mach-Zehnder intensity modulator. ECL: external-cavity CW laser, VOA: variable optical attenuator.

Setup of the P-OTDR measurement (a) and the measured traces for two different adjustments of PC (b). Smooth traces without any ripple in the CB-HNLF section clearly indicates that the ellipticity of polarization is maintained excellently along CB-HNLF.

(a) Optical spectra observed at the CB-HNLF input (broken), output (bold black and gray), and after the BPF (thin) (resolution = 0.1 nm). The polarization scrambler is turned off. The black and gray bold curves show the two extreme cases where the XPM-induced spectral broadening of the CW light became the maximum and minimum as we vary the input signal SOP using PC1. (b) Eye diagrams of the 160-Gb/s wavelength-converted signal with the polarization scrambler OFF (left) and ON (right).

Autocorrelation traces of the input (left) and wavelength-converted (right) signals.

(a) Eye-diagrams of a demultiplexed tributary with the polarization scrambler OFF (left) and ON (right). (b) Receiver sensitivities for all tributaries with the polarization scrambler OFF (circles) and ON (dots). (c) BER curves for the best (Ch5, circles) and worst (Ch11, triangles) tributaries of the wave-length-converted signal with the polarization scrambler OFF (white) and ON (black).
