nano-optics is an emergent research field in physics that appeared in the 1980s,which deals with light–matter optical interactions at the nanometer scale.In early studies of nano-optics,the main concern focus is to obtain higher optical resolution over the diffraction limit.The researches of near-field imaging and spectroscopy based on scanning near-field optical microscopy(SNOM)are developed.The exploration of improving SNOM probe for near-field detection leads to the emergence of surface plasmons.In the sense of resolution and wider application,there has been a significant transition from seeking higher resolution microscopy to plasmonic near-field modulations in the nano-optics community during the nano-optic development.Nowadays,studies of nano-optics prefer the investigation of plasmonics in different material systems.In this article,the history of the development of near-field optics is briefly reviewed.The difficulties of conventional SNOM to achieve higher resolution are discussed.As an alternative solution,surface plasmons have shown the advantages of higher resolution,wider application,and flexible nano-optical modulation for new devices.The typical studies in different periods are introduced and characteristics of nano-optics in each stage are analyzed.In this way,the evolution progress from near-field optics to plasmonics of nano-optics research is presented.The future development of nano-optics is discussed then.

A polarizing situation： Taking an in-plane perspective for next-generation near-field studies

By enabling the probing of light-matter interactions at the functionally relevant length scales of most materials, near-field optical imaging and spectroscopy accesses information that is unobtainable with other methods. The advent of apertureless techniques, which exploit the ultralocalized and enhanced near-fields created by sharp metallic tips or plasmonic nanoparticles, has resulted in rapid adoption of near-field approaches for studying novel materials and phenomena, with spatial resolution approaching sub-molecular levels. However, these approaches are generally limited by the dominant out-of-plane polarization response of apertureless tips, restricting the exploration and discovery of many material properties. This has led to recent design and fabrication breakthroughs in near-field tips engineered specifically for enhancing in-plane interactions with near-field light components. This mini-review provides a perspective on recent progress and emerging directions aimed at utilizing and controlling in-plane optical polarization, highlighting key application spaces where in-plane near-field tip responses have enabled recent advancements in the understanding and development of new nanostructured materials and devices.

Review: Physical Coloration-nanoscopic Science and Macroscopic Impact

引用

Journal of Harbin Institute of Technology(New Series) 2021年第1期28卷 1-11页

作者： Jimmy Xu School of Engineering and Department of Physics Brown UniversityProvidenceRhode Island 02912USA

Physical coloration stimulated the development of a new era of science and technology some hundred years earlier.It is now again presenting us new opportunities and challenges on multiple fronts.This article focuses on a selectively few of them that are more directional in nature:scalable nanomanufacturing of physical coloration,physical amplification of colorimetric sensing,and provision of biophilic lighting with real-time full-spectrum physical coloration.Physical coloration is a rather large multi-dimensional field that is open and awaiting for creative minds and hands.Its impact has been broad and profound to the well-being of humankind.This article attempts to complement the reviews of broad scopes available in literature by one with a narrower focus on the more recent advances on the three fronts.
