Outline of Final Research Achievements

This project aimed to propose and demonstrate a new method to measure the energy flow across the cross section of optical beams. Vortex inversion during free-space propagation was chosen as the target, and angular momentum measurement by a rotational shearing interferometer as the method. The interferometer was built and alignment method was established. For a doughnut mode with azimuthal mode number m=1, angular momentum per power was successfully measured quantitatively. Quantitative measurement was not achieved for the more complex vortex inversion phenomenon, but it should be possible by improving the system to allow smaller shear angles. We were also able to formalize the method as a weak measurement, and confirmed amplification of weak value in the form of phase gradient in the azimuthal direction.

Academic Significance and Societal Importance of the Research Achievements

本手法により、光ビームの角運動量分布の定量的な測定が可能であることが示された。複雑な構造をもつビームについてはまだ測定に成功していないが、今後の改良で克服可能と考えられる。これにより光ビームのもつ力学的な性質の評価・活用が進むことが期待される。
本研究ではまた、光の角運動量分布測定を弱測定の枠組みの中に位置付けることができた。これにより、方位角方向の位相勾配を弱値として特定することができ、弱値の増幅についても確認することができた。これらはシア干渉計一般を弱測定の枠組みでとらえることが可能であることを示唆するものであり、学術的な意義は大きい。
