Uniqueness and modified Newton method for cracks from the far field patterns with a fixed incident direction

Autor: Li, Jialei, Liu, Xiaodong

We consider the inverse cracks scattering problems from the far field patterns with a fixed incident direction. We firstly show that the sound-soft cracks can be uniquely determined by the multi-frequency far field patterns with a fixed incident dire

Advanced Equalization in 112 Gb/s Upstream PON Using a Novel Fourier Convolution-based Network

Autor: Shao, Chen, Giacoumidis, Elias, Matalla, Patrick, Li, Jialei, Li, Shi, Randel, Sebastian, Richter, Andre, Faerber, Michael, Kaefer, Tobias

We experimentally demonstrate a novel, low-complexity Fourier Convolution-based Network (FConvNet) based equalizer for 112 Gb/s upstream PAM4-PON. At a BER of 0.005, FConvNet enhances the receiver sensitivity by 2 and 1 dB compared to a 51-tap Sato e

Machine Learning in Short-Reach Optical Systems: A Comprehensive Survey

Autor: Shao, Chen, Giacoumidis, Elias, Billah, Syed Moktacim, Li, Shi, Li, Jialei, Sahu, Prashasti, Richter, Andre, Kaefer, Tobias, Faerber, Michael

In recent years, extensive research has been conducted to explore the utilization of machine learning algorithms in various direct-detected and self-coherent short-reach communication applications. These applications encompass a wide range of tasks,

A Novel Machine Learning-based Equalizer for a Downstream 100G PAM-4 PON

Autor: Shao, Chen, Giacoumidis, Elias, Li, Shi, Li, Jialei, Faerber, Michael, Kaefer, Tobias, Richter, Andre

A frequency-calibrated SCINet (FC-SCINet) equalizer is proposed for down-stream 100G PON with 28.7 dB path loss. At 5 km, FC-SCINet improves the BER by 88.87% compared to FFE and a 3-layer DNN with 10.57% lower complexity.

Rectangular carbon nitrides C4N monolayers with a zigzag buckled structure: Quasi-one-dimensional Dirac nodal lines and topological flat edge states

Autor: Li, Linyang, Li, Jialei, Yu, Yawei, Song, Yuxuan, Li, Jia, Liu, Xiaobiao, Peeters, François M., Chen, Xin, Liu, Guodong

Due to the flexibility of C and N atoms in forming different types of bonds, the prediction of new two-dimensional (2D) carbon nitrides is a hot topic in the field of carbon-based materials. Using first-principles calculations, we propose two C4N mon
