Single-mode, long-wavelength vertical-cavity surface-emitting lasers (VCSELs) in the near- to mid-infrared covering the wavelength range from 1.3 to 2.3 \mum are presented. This wide spectral emission range opens applications in gas sensing and optical i
今年的诺贝尔物理奖金获得者中有两人是哈佛大学的布隆伯根(N. Bbembergen)和斯坦福大学的肖洛(A. L. Schawlow),他们分享了1981年度奖金的一半(另一半奖金由研究电子谱的瑞典乌普萨拉大学的KaiSiegbahri获得)。评奖委员会奖状中仅暗示他们对激光科学的基础贡献,却写明他们在“激光光谱学”方面的工作。他俩均把这次获奖看作对他们在此领域广泛成就的承认,而不是对某项特定工作的承认。
We present the long-term stability of the integrating sphere cold atom clock (ISCAC) and analyze its systematic limitations. The relative frequency instability of
The importance of tunable subwavelength optical devices in modern electromagnetic and photonic systems is indisputable. Herein, a lithography-free, wide-angle, and reconfigurable subwavelength optical device with high tunability operating in the near-infr
