光集成和光集成器件是当前科技领域的前沿课题,它将光学、微波、激光、微电子学以及光电子学等多个技术领域紧密结合,形成一个创新的交叉学科。这篇由苏方宁和邓再德撰写的论文深入探讨了光集成的概念。光集成不仅涵盖了基础理论,如光信号的传输和处理,还包括了实际应用,如在光通信系统中的关键作用,通过集成化的光学组件提高信号处理效率和设备小型化。 文章首先介绍了光集成的基本定义,它是通过微加工技术,将光的产生、操控和检测等功能集成到一个小型的硅基或其他材料平台上,从而实现光信号的高效管理和控制。这种集成方式使得系统设计更加简洁,成本更低,同时也提高了系统的稳定性和可靠性。 光集成的主要应用领域广泛,包括但不限于光纤通信、数据通信、光计算、生物医学成像、传感器技术和量子信息科学等。在光纤通信中,光集成器件如光调制器、解调器、开关和滤波器等是构建高速、高容量光网络的关键组件。此外,随着微电子技术的进步,光集成还在推动光子芯片的发展,这些芯片有望实现更复杂的光信号处理功能。 论文还着重分析了当前的研究热点,这可能包括新型光集成材料的研发、集成工艺的改进、新型光器件的设计以及与人工智能和大数据结合的应用探索。作者强调,抓住光电子技术发展的大好机遇,大力发展我国的光集成器件对于推动我国光通信行业的发展具有重大战略意义,不仅能够提升国家在全球通信技术竞争中的地位,还能促进产业升级,带动相关产业链的经济增长。 关键词“光集成”、“光集成器件”、“光通信”、“研究热点”和“研究进展”突显了论文的核心内容,强调了中国在这个领域必须采取积极行动,紧跟国际前沿,加强技术研发,以确保在未来的光通信行业中保持领先地位。 这篇论文深入解析了光集成的基础理论、应用前景以及发展策略,对于理解光集成技术的现状和未来趋势具有重要的参考价值。对于从事光通信、微电子和光电子学相关研究的专业人士,以及关注技术发展和国家战略性新兴产业布局的决策者来说,这篇论文无疑提供了宝贵的知识和洞见。

润色下面英文:The controlled drug delivery systems, due to their precise control of drug release in spatiotemporal level triggered by specific stimulating factors and advantages such as higher utilization ratio of drug, less side-effects to normal tissues and so forth, provide a new strategy for the precise treatment of many serious diseases, especially tumors. The materials that constitute the controlled drug delivery systems are called “smart materials” and they can respond to the stimuli of some internal (pH, redox, enzymes, etc.) or external (temperature, electrical/magnetic, ultrasonic and optical, etc.) environments. Before and after the response to the specific stimulus, the composition or conformational of smart materials will be changed, damaging the original balance of the delivery systems and releasing the drug from the delivery systems. Amongst them, the photo-controlled drug delivery systems, which display drug release controlled by light, demonstrated extensive potential applications, and received wide attention from researchers. In recent years, photo-controlled drug delivery systems based on different photo-responsive groups have been designed and developed for precise photo-controlled release of drugs. Herein, in this review, we introduced four photo-responsive groups including photocleavage groups, photoisomerization groups, photo-induced rearrangement groups and photocrosslinking groups, and their different photo-responsive mechanisms. Firstly, the photocleavage groups represented by O-nitrobenzyl are able to absorb the energy of the photons, inducing the cleavage of some specific covalent bonds. Secondly, azobenzenes, as a kind of photoisomerization groups, are able to convert reversibly between the apolar trans form and the polar cis form upon different light irradiation. Thirdly, 2-diazo-1,2-naphthoquinone as the representative of the photo-induced rearrangement groups will absorb specific photon energy, carrying out Wolff rearrangement reaction. Finally, coumarin is a promising category photocrosslinking groups that can undergo [2+2] cycloaddition reactions under light irradiation. The research progress of photo-controlled drug delivery systems based on different photo-responsive mechanisms were mainly reviewed. Additionally, the existing problems and the future research perspectives of photo-controlled drug delivery systems were proposed.
