New #OPG_Optica research introduces a new method to address the sampling rate limitations of a single camera and eliminate temporal inaccuracies during biological fluorescence imaging: https://bit.ly/4kl3ysU A Peking University team leveraged a two-camera recording with galvo mirror-based parallel projection to produce a near-square FoV that extends more than three times the size of conventional rolling shutter imaging. The ROSE-based high-speed imaging method provides crucial benefits for live-cell imaging, such as optimizing two-dimensional acquisition in a single frame, thereby improving monitoring of radial regions of interest.

This polarization-independent arrayed waveguide grating (AWG) spectrometer could enable wide applications in coherent astrophotonics, sensing and spectroscopy: https://bit.ly/4exphwp As described in #OPG_OPTCON, the spectrometer splits two orthogonal polarization portions with a polarization splitter, then processes and merges them with an on-chip multi-input AWG. As a result, the University of Maryland team could demultiplex an arbitrary polarized signal with a stable throughput of around 60% Written by: Xiheng Ai, Wei-Lun Hsu, Yang Zhang, Sylvain Veilleux, and Mario Dagenais #scienceandtechnology #spectroscopy #polarization

What is molecular beam epitaxy synthesis, and how can it transform next-generation THz platforms? https://bit.ly/3TSrAk3 As discussed in #OPG_OMEx, topological materials are excellent candidates for developing terahertz (THz) optoelectronic components due to their topologically protected surface states and strong spin-orbit coupling. The robust and topologically protected gapless surface states in these materials enable ultrafast carrier transport characteristics, along with unique plasmonic and nonlinear optical properties.

This wearable device enables cuffless blood pressure monitoring: https://bit.ly/44yQBWA. Using speckle contrast optical spectroscopy, the device non-invasively gathers information about blood flow and volume to measure blood pressure more accurately than traditional cuff devices. Next, the Boston University team plans to develop a wearable version of this technology, groundwork for continuous tracking of cardiovascular health. #OPG_BOEx #healthcare #bloodpressure #medicine

Last week, I attended the Optica Women Scholars Conference and the Laser World of Photonics Conference in Munich, Germany! It was a busy week involving motivational talks on professional development and supporting women in optics. This was a wonderful opportunity to learn from these incredible mentors and leaders. I am also grateful to my peers in the Optica Women Scholars program who continuously created a welcoming and empowering atmosphere. Thank you to Optica for this opportunity, and thank you to Sarah Moore and John Taylor for organizing our involvement in this conference!

In an era of increasingly large models and big data, optical fiber communication backbone networks require remarkable security - How can it be improved? https://bit.ly/40lM5cP To build upon current QNSC schemes, which lag behind the existing 400G optical fiber backbone network, 上海交通大学 researchers incorporated QNSC with deep learning. Their end-to-end QNSC boasts secure optical communication with a single-channel rate of 400 Gbps, a total capacity of 8.4 Tbps, and a transmission distance of 1520 km, achieving the highest rate–distance product record of QNSC secure transmission systems.
