100 Gigabit Internet why and how : the technology behind it [PDF]

open access: yes, 2010
The need to keep transmission capacity growing is a never ending process which is becoming more and more challenging to fulfill. Over the years we have witnessed data rates to grow from less than one bit per second all the way up to tens of Giga bits per

Rare Earth Doped Optical Fibers with Multi-section Core

open access: yesiScience, 2019
Summary: The gain bandwidth of a single-mode fiber is limited by the atomic transitions of one rare earth gain element. Here we overcome this long-standing challenge by designing a new single-mode fiber with multi-section core, where each section is ...

A Novel Noise-Insensitive Chromatic Dispersion Estimation Method Based on Fractional Fourier Transform of LFM Signals

open access: yesIEEE Photonics Journal, 2017
We propose a novel chromatic dispersion (CD) estimation method by fractional Fourier transformation of linear-frequency modulation (LFM) signals. This method can measure inband and outband CD without using extra spectrum or timeslot resourses.

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

open access: yesIEEE 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-
