近年来,基于不同光子集成平台和光开关规模的研究激增,通道数和开关速率都有显著突破,然而过去所报道的集成光开关芯片的插损(IL)、偏振相关损耗(PDL)、串扰(Crosstalk)、带宽(Bandwidth)和一致性(Uniformity)等性能仍然与商用指标有很大差距,难以替代当前商用的基...

Transition metal dichalcogenides are optically active, layered materials promising for fast optoelectronics and on-chip photonics. We demonstrate electrically driven single-photon emission from localized sites in tungsten diselenide and tungsten disulphi
Optical cycles are much too fast to allow direct temporal light shaping, while direct modulation of the wavelength bandwidth lacks sophistication (mostly based on thin-film interference and absorption). For this reason, temporal light shaping reduces to spatial light shaping of the frequency components...

Light nodes usually only need up to 100 GB SSD, 4 GB RAM, a dual-core CPU or equivalent processing power, and an Internet connection with moderate bandwidth in the megabytes or gigabytes per second to download and synchronize with the blockchain network.7Full nodes and master nodes require a...
