Adaptive optical microscopy via virtual-imaging-assisted wavefront sensing for high-resolution tissue imaging
PhotoniX - - 2022
Zhou Zhou, Jiangfeng Huang, Xiang Li, Xiujuan Gao, Zhongyun Chen, Zhenfei Jiao, Zhihong Zhang, Luo Qinghong, Ling Fu
AbstractAdaptive optics (AO) is a powerful tool for optical microscopy to counteract the effects of optical aberrations and improve the imaging performance in biological tissues. The diversity of sample characteristics entails the use of different AO schemes to measure the underlying aberrations. Here, we present an indirect wavefront sensing method leveraging a vi...... hiện toàn bộ

Nonlinear meta-optics towards applications
PhotoniX - Tập 2 - Trang 1-20 - 2021
Yun Zhao, Yuanmu Yang, Hong-Bo Sun
Nonlinear optical effects have enabled numerous applications such as laser frequency conversion, ultrafast electro-optical, and all-optical modulation. Both gaseous and bulk media have conventionally been used for free-space nonlinear optical applications, yet they often require complex phase-matching techniques for efficient operation and may have limited operation bandwidth due to the material a...... hiện toàn bộ
Review: distributed time-domain sensors based on Brillouin scattering and FWM enhanced SBS for temperature, strain and acoustic wave detection
PhotoniX - Tập 2 - Trang 1-29 - 2021
Xiaoyi Bao, Zichao Zhou, Yuan Wang
Distributed time-domain Brillouin scattering fiber sensors have been widely used to measure the changes of the temperature and strain. The linear dependence of the temperature and strain on the Brillouin frequency shift enabled the distributed temperature and strain sensing based on mapping of the Brillouin gain spectrum. In addition, an acoustic wave can be detected by the four wave mixing (FWM) ...... hiện toàn bộ
Metamaterial anapole plasmon học cho cảm biến chỉ số khúc xạ Dịch bởi AI

Jin Yao, Jun‐Yu Ou, Vassili Savinov, Mu Ku Chen, Hsin Yu Kuo, Nikolay I. Zheludev, Din Ping Tsai
Tóm tắtChế độ anapole điện từ là một trạng thái ánh sáng không phát xạ, bắt nguồn từ sự can thiệp hủy diệt của bức xạ từ các mô men điện và mô men tẩm hình toro đang dao động. Các cộng hưởng liên quan đến anapole chất lượng cao có thể được sử dụng để tăng cường các đặc tính điện từ phi tuyến của vật liệu và trong các ứng dụng cảm biến. Trong công trình này, chúng t...... hiện toàn bộ
Multiplexing near- and far-field functionalities with high-efficiency bi-channel metasurfaces
PhotoniX - Tập 5 Số 1
Congqi Dai, Tong Liu, Dongyi Wang, Lei Zhou
AbstractPropagating waves and surface waves are two distinct types of light-transporting modes, the free control of which are both highly desired in integration photonics. However, previously realized devices are bulky in sizes, inefficient, and/or can only achieve one type of light-manipulation functionality with a single device. Here, we propose a generic approac...... hiện toàn bộ
Ultrafast dissipative soliton generation in anomalous dispersion achieving high peak power beyond the limitation of cubic nonlinearity
PhotoniX - Tập 4 - Trang 1-18 - 2023
Jinhwa Gene, Seung Kwan Kim, Sun Do Lim, Min Yong Jeon
The maximum peak power of ultrafast mode-locked lasers has been limited by cubic nonlinearity, which collapses the mode-locked pulses and consequently leads to noisy operation or satellite pulses. In this paper, we propose a concept to achieve mode-locked pulses with high peak power beyond the limitation of cubic nonlinearity with the help of dissipative resonance between quintic nonlinear phase s...... hiện toàn bộ
Realization of high aspect ratio metalenses by facile nanoimprint lithography using water-soluble stamps
PhotoniX - Tập 4 - Trang 1-11 - 2023
Hojung Choi, Joohoon Kim, Wonjoong Kim, Junhwa Seong, Chanwoong Park, Minseok Choi, Nakhyun Kim, Jisung Ha, Cheng-Wei Qiu, Junsuk Rho, Heon Lee
Nanoimprint lithography (NIL) has attracted attention recently as a promising fabrication method for dielectric metalenses owing to its low cost and high throughput, however, high aspect ratio (HAR) nanostructures are required to manipulate the full 2π phase of light. Conventional NIL using a hard-polydimethylsiloxane (h-PDMS) mold inevitably incurs shear stress on the nanostructures which is inve...... hiện toàn bộ

Vacuum-ultraviolet photodetectors
PhotoniX - - 2020
Lemin Jia, Wei Zheng, Feng Huang
Abstract High-performance vacuum-ultraviolet (VUV) photodetectors are of great significance to space science, radiation monitoring, electronic industry and basic science. Due to the absolute advantages in VUV selective response and radiation resistance, ultra-wide bandgap semiconductors such as diamond, BN and AlN attract wide interest from researcher...... hiện toàn bộ
