Silicon core fibre is a highly nonlinear waveguide that combines the benefits of both fibre and planar waveguide systems. Here, the authors demonstrate frequency comb generation using a fully-fibre integrated silicon core fibre as a nonlinear mixer.

We present a novel methodology for optimizing fiber optic network performance by determining the ideal values for attenuation, nonlinearity, and dispersion parameters in terms of achieved signal-to-noise ratio (SNR) gain from digital backpropagation

A pump dithering removal algorithm, based on pilot sequence-aided DSP, is proposed and experimentally validated in dual polarization 64 QAM optical phase conjugation system. A 4.2 dB SNR improvement was observed due to the SBS suppression.

We design and optimize a parametric frequency comb generator using all polarization- maintaining components, highly-doped PM fiber and PM highly-nonlinear fibers, obtaining 500 tones over 100nm with >-5dBm per tone and less than 40kHz linewidth.

We investigated the impact of linewidth and dithering-induced frequency variation on the performance of nonlinearity mitigation using frequency combs. Compared to independent laser arrays, >2dB SNR gain can be achieved using comb sources.

Optical switching has the potential to scale the capacity of data center networks (DCN) with a simultaneously reduction in latency and power consumption. One of the main challenges of optically-switched DCNs is the need for fast clock and data recove
