Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Mingxiao Li, Lin Chang, Lue Wu, Jeremy Staffa, Jingwei Ling | Summary: The development of integrated semiconductor lasers has miniaturized traditional bulky laser systems, enabling a wide range of photonic applications. A progression from pure III-V based lasers to III-V/external cavity structures has harnessed low-loss waveguides […]
Kavli Affiliate: Wei Gao | First 5 Authors: Wenbo Zhao, Xianming Liu, Zhiwei Zhong, Junjun Jiang, Wei Gao | Summary: Point clouds upsampling is a challenging issue to generate dense and uniform point clouds from the given sparse input. Most existing methods either take the end-to-end supervised learning based manner, where large amounts of pairs […]
Kavli Affiliate: Scott K. Cushing | First 5 Authors: Isabel M. Klein, Hanzhe Liu, Danika Nimlos, Alex Krotz, Scott K. Cushing | Summary: Transient X-ray and extreme ultraviolet (XUV) spectroscopies have become invaluable tools for studying photoexcited dynamics due to their sensitivity to carrier occupations and local chemical or structural changes. One of the most […]
Kavli Affiliate: Lihong Wang | First 5 Authors: Xuan Zhang, Tingdi Ren, Lihong Wang, Haiyong Xu, | Summary: Studying the history of music may provide a glimpse into the development of human creativity as we examine the evolutionary and revolutionary trends in music and genres. First, a musical influence metric was created to construct a […]
Kavli Affiliate: Wei Gao | First 5 Authors: Ruichao Yang, Jing Ma, Hongzhan Lin, Wei Gao, | Summary: The diffusion of rumors on microblogs generally follows a propagation tree structure, that provides valuable clues on how an original message is transmitted and responded by users over time. Recent studies reveal that rumor detection and stance […]

Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Costa, Zhongwen Zhan, Alireza Marandi, , | Summary: Fiber optic distributed sensors typically demand bidirectional propagation in optical fibers to localize each point of measurement. This imposes barriers to their deployment in long-haul, amplified telecommunication links and prevents massive range enhancement through in-line amplification, due to […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Costa, Zhongwen Zhan, Alireza Marandi, , | Summary: Simultaneously sensing and resolving the position of measurands along an optical fiber enables numerous opportunities, especially for application in environments where massive sensor deployment is not feasible. Despite significant progress in techniques based on round-trip time-of-flight measurements, the […]
Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Joel Guo, Charles A. McLemore, Chao Xiang, Dahyeon Lee, Lue Wu | Summary: Lasers with hertz-level linewidths on timescales up to seconds are critical for precision metrology, timekeeping, and manipulation of quantum systems. Such frequency stability typically relies on bulk-optic lasers and reference cavities, where increased […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Semih Taniker, Vincenzo Costanza, Paolo Celli, Chiara Daraio, | Summary: We propose the realization of capacitive temperature sensors based on the concept of displacement amplification. Our design features two high coefficient of thermal expansion (CTE) metallic layers separated by a low-CTE dielectric layer; conductive and dielectric layers […]
