On the Cover: Ultra-broadband near-infrared NOPAs based on the nonlinear crystals BiBO and YCOB

The image on the cover of High Power Laser Science and Engineering Volume 8, Issue 3, evaluates and demonstrates ultra-broadband near-infrared noncollinear optical parametric amplification in two nonlinear crystals, bismuth borate (BiBO) and yttrium calcium oxyborate (YCOB), which are not commonly used for this application. Provided by M. Galletti et al., researchers from Universidade de Lisboa, Harwell Science and Innovation Campus and INFN-LNF, the image is based on the research presented in their article, "Ultra-broadband near-infrared NOPAs based on the nonlinear crystals BiBO and YCOB", High Power Laser Science and Engineering 8(3) 03000e29, doi 10.1017/hpl.2020.27.

On the Cover: First-Stokes and second-Stokes multi-wavelength continuous-wave operation in Nd:YVO4/BaWO4 Raman laser under in-band pumping

The image on the cover of Chinese Optics Letters Volume 18, Issue 11, indicates that a continuous-wave Nd:YVO4/BaWO4 Raman laser generating simultaneous multi-wavelength first-Stokes and second-Stokes emissions is demonstrated for the first time, to the best of our knowledge. Investigations concerning different pump spot sizes and crystal lengths were conducted to improve the thermal effect and pump absorption. Provided by L. Fan et al., researchers from Yangzhou University, the image is based on the research presented in their article, "First-Stokes and second-Stokes multi-wavelength continuous-wave operation in Nd:YVO4/BaWO4 Raman laser under in-band pumping", Chinese Optics Letters 18(11) 111401, doi 10.3788/COL202018.111401.

On the Cover: Cavity engineering of two-dimensional perovskites and inherent light-matter interaction

The image on the cover of Photonics Research Volume 8, Issue 11, indicates that two-dimensional (2D) perovskites are hybrid layered materials in which the inorganic lattice of an octahedron is sandwiched by organic layers. They behave as a quantum-well structure exhibiting large exciton binding energy and high emission efficiency, which is excellent for photonic applications. Provided by S. Zhang et al., researchers from National Center for Nanoscience and Technology, University of Chinese Academy of Sciences, Tianjin University and Zhejiang University, the image is based on the research presented in their article , "Cavity engineering of two-dimensional perovskites and inherent light-matter interaction", Photonics Research 8(11) 11000A72, doi 10.1364/PRJ.400259.

On the Cover: Dynamic photonic barcodes for molecular detection based on cavity-enhanced energy transfer

The image on the cover for Advanced Photonics Volume 2, Issue 6, illustrates the concept of optical encoding with microdroplets controlled by energy transfer at the biointerface. The image is based on original research presented by Yunke Zhou, Zhiyi Yuan, Xuerui Gong, Muhammad D. Birowosuto, Cuong H. Dang, and Yu-Cheng Chen in their paper “Dynamic photonic barcodes for molecular detection based on cavityenhanced energy transfer,” Adv. Photon. 2(6), 066002, doi: 10.1117/1.AP.2.6.066002.

On the Cover: Single-photon computational 3D imaging at 45 km

The image on the cover of Photonics Research Volume 8, Issue 9, indicates that Single-photon light detection and ranging (lidar) offers single-photon sensitivity and picosecond timing resolution, which is desirable for high-precision three-dimensional (3D) imaging over long distances. Despite important progress, further extending the imaging range presents enormous challenges because only a few echo photons return and are mixed with strong noise. Provided by Z. Li et al., researchers from University of Science and Technology of China and Shanghai Research Center for Quantum Sciences, the image is based on the research presented in their article, "Single-photon computational 3D imaging at 45 km", Photonics Research 8(9) 09001532, doi 10.1364/PRJ.390091.

On the Cover: Optical studies of semiconductor perovskite nanocrystals for classical optoelectronic applications and quantum information technologies: a review

The image on the cover of Advanced Photonics Volume 2, Issue 5, illustrates the collective optical properties of semiconductor perovskite nanocrystals under the excitation of upper blue laser ray. The cubic perovskite nanocrystals exhibit amplified spontaneous emission (ASE) tunable from near UV to near Infrared on the right side. Three sequential bright dots and decaying sinusoidal wave on the lower side represent single photon emission and quantum coherence in perovskite nanocrystals, respectively. Meanwhile, the discrete energy levels and photoluminescence spectrum on the left side correspond to the fine structure of perovskite nanocrystals. Provided by Z. Cao et al., researchers from Nanjing University and University of Arkansas, the image is based on the research presented in their article, "Optical studies of semiconductor perovskite nanocrystals for classical optoelectronic applications and quantum information technologies: a review", Adv. Photon. 2(5) 054001. doi 10.1117/1.AP.2.5.054001.
