Outline of Research at the Start

光の角運動量選択は量子通信・暗号化に不可欠な要素である。本研究では、この光の角運動量を定量検出するソーターを作製し実証する。これまで角運動量選択には、対掌性をもつキラル構造が提案されてきたが左右回転パリティへの応答が同等でなく、定量性・堅牢性に欠けていた。今回、アキラルな構造を用いた光アンテナ・導波路を用いて、両パリティに同等に応答する角運動量ソーターを実現する。この計測のために、光のエネルギー・励起位置・発光位置・発光角度の全情報を同時に得られる多空間同時計測カソードルミネセンスを開発する。

Outline of Final Research Achievements

Selection of optical angular momentum is an essential element for next-generation communication and encryption. While chiral structures with a specific handedness have been proposed for optical angular momentum selection, their responses to left or right circular polarization are not equivalent, thus requiring a different structure for each parity. In this study, we utilized achiral nanostructures for controlling optical angular momentum of light. Furthermore, we developed a novel cathodoluminescence measurement method, which allows analyzing optical properties of nanostructures far beyond the diffraction limit of light with various light detection functions. Using this technique, we investigated the chiral optical properties of symmetric nanoantennas and waveguides, and confirmed their equivalent and selective chiral characteristics for both parities.

Academic Significance and Societal Importance of the Research Achievements

光の角運動量を制御する研究はここ数年、通信だけでなく超解像顕微法、トラッピング、量子状態の選択など、応用から基礎まで広く注目を集めている。しかし、角運動量選択デバイスとしての研究は、フォトニック結晶におけるトポロジカルな導波路を除いては、キラルな構造あるいはキラルな物質を用いたものしか存在しない。本研究のアキラル構造の積極的な活用は、両方のパリティの角運動量を同等抽出するデバイスを実現するという点で学術的にも技術的にも極めてユニークで先進的な研究である。また、本研究で開発したカソードルミネセンスによる光計測法は、世界最先端な手法であり、他の追随を許さない。
