Polarization-Insensitive Phase-Transmultiplexing and Multicasting of CSRZ-OOK and 4 $\times$ RZ-BPSK to 4 $\times$ RZ-QPSK via XPM in a Birefringent PCF

IEEE Photonics Journal, 2014
By utilizing cross-phase modulation and birefringence, we demonstrated simultaneous polarization-insensitive phase-transmultiplexing and multicasting of a single 10-Gbaud CSRZ-OOK signal and 4 $\times$ 10-Gbaud RZ-BPSK signals to generate 4 $\times$ 10-

Multi-element fiber for space-division multiplexed optical communication system [PDF]

, 2014
This paper reviews a novel approach of implementing space-division multiplexing (SDM) based on Multi-element Fiber (MEF) technology. The MEF geometry provides for ultra-low crosstalk between the spatial channels while full compatibility with standard WDM

Training Sequence-Based Chromatic Dispersion Estimation With Ultra-Low Sampling Rate for Optical Fiber Communication Systems

IEEE Photonics Journal, 2018
We present a novel method to estimate chromatic dispersion with ultra-low sampling rate based on training sequence. The under-sampling can be equivalent to over-sampling by splicing points with periodic sequence.

Simultaneous Measurement of Shape and Temperature in the Substrate-Attaching-Fibers Sensing System

IEEE Photonics Journal, 2017
We design a dual-parameter sensor which can simultaneously measure the shape and temperature in the substrate-attaching-fibers sensing system. Two kinds of fibers with different diameter are attached on a shape memory alloy wire substrate with an angle ...
