In-situ aligned all-polarization-maintaining Er-doped fiber laser mode-locked by a nonlinear amplifying loop mirror

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Kangrui Chang, Haobin Zheng, Yongzhuang Zhou, Yong Shen | Summary: Despite the wide applications for high-repetition-rate mode-locked fiber lasers, challenges persist in shortening the cavity length and coupling the fiber collimators for most existing techniques. Here, we introduce a novel collimator alignment method and demonstrate […]

The graphene squeeze-film microphone

Kavli Affiliate: P. G. Steeneken | First 5 Authors: M. P. Abrahams, J. Martinez, P. G. Steeneken, G. J. Verbiest, | Summary: Most microphones operate by detecting the sound-pressure induced motion of a membrane. In contrast, here we introduce a microphone that operates by monitoring the sound-pressure-induced modulation of the compressibility of air. By driving […]

Joint Power Allocation and Beamforming Design for Active IRS-Aided Directional Modulation Secure Systems

Kavli Affiliate: Wei Gao | First 5 Authors: Yifan Zhao, Xiaoyu Wang, Kaibo Zhou, Xuehui Wang, Yan Wang | Summary: Since the secrecy rate (SR) performance improvement obtained by secure directional modulation (DM) network is limited, an active intelligent reflective surface (IRS)-assisted DM network is considered to attain a high SR. To address the SR […]

Chain of Preference Optimization: Improving Chain-of-Thought Reasoning in LLMs

Kavli Affiliate: Wei Gao | First 5 Authors: Xuan Zhang, Chao Du, Tianyu Pang, Qian Liu, Wei Gao | Summary: The recent development of chain-of-thought (CoT) decoding has enabled large language models (LLMs) to generate explicit logical reasoning paths for complex problem-solving. However, research indicates that these paths are not always deliberate and optimal. The […]
