Optical PAM-4/PAM-8 generation via dual-Raman process in Rydberg atoms

引用

Chinese Physics B 2024年第6期33卷 383-388页

作者：宋晓云尹政任冠宇韩明志杨艾红祁义红彭延东 Qingdao Key Laboratory of Terahertz Technology College of Electronic and Information EngineeringShandong University of Science and TechnologyQingdao 266590China School of Physics East China University of Science and TechnologyShanghai 200237China MIIT Key Laboratory of Complex-field Intelligent Exploration Beijing Institute of TechnologyBeijing 100081China

A scheme of optical four-level pulse amplitude modulation(PAM-4) is proposed based on dual-Raman process in Rydberg atoms. A probe field counter-propagates with a dual-Raman field which drives the ground and the excited states transition, respectively, and the Rydberg transition is driven by a microwave(MW) field. A gain peak appears in the probe transmission and is sensitive to the MW field strength. Optical PAM-4 can be achieved by encoding an MW signal and decoding the magnitude of a probe signal. Simulation results show that the differential nonlinearity and the integral nonlinearity of the proposed scheme can be reduced by 5 times and 6 times, respectively, compared with the counterparts of previous scheme, and the ratio of level separation mismatch is close to the ideal value 1. Moreover, the scheme is extended to optical PAM-8 signal, which may further improve the spectral efficiency.

我国目前虽然已初步构建起规制侦查机关收集通信信息的法律体系,但这一体系未能较好地因应数字时代的发展趋势,存在诸多不足。在数字时代,多元化样态的通信信息背后承载着不同的保护法益。立法者应当区分这些不同的保护法益,依循通信信息类型的本质特征,作出合乎比例的、有针对性的法律规制。具体而言,我国应从如下方面加强法律规制:一是由刑事诉讼法为某些新型侦查措施提供特别授权依据,以符合宪法要求;二是按照通信信息类型的不同,以比例原则为指导进行相应密度的法律规制;三是大幅度提升扣押邮件、电报措施的法律规制密度;四是对查看嫌疑人手机通信内容信息的行为进行独立授权;五是建立符合《个人信息保护法》要求的相应保护机制。

Quantitative analysis of activated neurons in mouse brains by a specific stimulation is usually a primary step to locate the responsive neurons throughout the brain. However, it is challenging to comprehensively and consistently analyze the neuronal activity trace in whole brains of a large cohort of mice from many terabytes of volumetric imaging data. Here, we introduce NEATmap, a deep learning–based high-efficiency,high-precision and user-friendly software for whole-brain neuronal activity trace mapping by automated segmentation and quantitative analysis of immunofluorescence labeled c-Fos+neurons. We applied NEATmap to study the brain-wide differentiated neuronal activation in response to physical and psychological stressors in cohorts of mice.
