Rapid progress in multi-core fibers and space division multiplexing technologies has enabled large-capacity transmission exceeding the conventional single-core fiber capacity limit of approximately 100 Tb/s. In this invited paper, we review such progress and achievements.

We propose and demonstrate a new Non-Decision Aid Modified Least Mean Square (NDA-MLMS) algorithm for joint blind equalization and carrier recovery. The bit error rate (BER) of 10-3 is achieved with less than 1.9dB OSNR penalty for 14Gbaud 4-QAM system after 100km transmission and 500 KHz linewidth laser.

This study demonstrates the high performance of GaAs solar cells with double-layer quantum dots carried by flexible PDMS film. Several parameters were enhanced. Different concentrations of QDs were also applied to test the optimal combination.

We demonstrate a hybrid design of InGaN/GaN multiple quantum well (MQW) solar cells combined with colloidal CdS quantum dots. With anti-reflective feature at long wavelength and down-conversion at UV regime, the CdS quantum dot effectively enhance the overall power conversion efficiency by as high as 7.2% compared to the no CdS quantum dots coated device.

A dual-band metamaterial absorber based on asymmetrical snowflake-shaped resonators is presented. The two absorption bands can be flexibly controlled by adjusting the branch lengths of the snowflake-shaped resonators. Full wave simulation and rigorous experiment are employed to demonstrate the proposed dual-band absorption characteristics.
