NTIRE 2021 Challenge on Quality Enhancement of Compressed Video: Methods and Results
Ren Yang, Radu Timofte, Jing Liu +69
This paper reviews the first NTIRE challenge on quality enhancement of compressed video, with a focus on the proposed methods and results. In this challenge, the new Large-scale Di…
High-speed silicon microring modulator at 2-um waveband
Weihong Shen, Gangqiang Zhou, Jiangbing Du +3
We demonstrated a silicon integrated microring modulator working at the 2-um waveband with an L-shaped PN junction. 15-GHz 3-dB electro-optic bandwidth and <1 Vcm modulation effici…
Comparison of phase change process in Si-GST hybrid integrated waveguide and MMI devices
Hanyu Zhang, Xing Yang, Liangjun Lu +3
In the past decades, silicon photonic integrated circuits (PICs) have been considered as a promising approach to solve the bandwidth bottleneck in optical communications and interc…
A silicon integrated microwave photonic beamformer
Chen Zhu, Liangjun Lu, Wensheng Shan +4
Optical beamforming networks (OBFNs) based on optical true time delay lines (OTTDLs) are well-known as the promising candidate to solve the bandwidth limitation of traditional elec…
Miniature Multi-Level Optical Memristive Switch Using Phase Change Material
Hanyu Zhang, Linjie Zhou, Liangjun Lu +6
The optical memristive switches are electrically activated optical switches that can memorize the current state. They can be used as optical latching switches in which the switchin…
Six-wave mixing induced by free-carrier plasma in silicon nanowire waveguides
Heng Zhou, Mingle Liao, Shu-Wei Huang +3
Nonlinear wave mixing in mesoscopic silicon structures is a fundamental nonlinear process with broad impact and applications. Silicon nanowire waveguides, in particular, have large…
