New mechanism for optical super-resolution via anisotropic near-zero index metamaterials

期刊: JOURNAL OF OPTICS, 2021; 23 (5)

In this paper, we propose a new mechanism for obtaining optical super-resolution based on anisotropic near-zero index metamaterials (AZIMs). It is fou......

A study of the origin of supercollimation in two-dimensional square-lattice photonic crystals

期刊: JOURNAL OF OPTICS, 2021; 23 (8)

The origin of the supercollimation (SC) phenomenon in two-dimensional photonic crystals (PhCs), which is generated by a weak periodic modulation of th......

From Imbert-Fedorov shift to topologically spin-dependent walking off for highly confining fiber-guided twisted light

期刊: JOURNAL OF OPTICS, 2021; 23 (6)

Light-matter interaction at dielectric interfaces usually manifests as spin-dependent correction to light propagation, known as classical Imbert-Fedor......

Beam collapse and refractive index changes inside fused silica induced by loosely focused femtosecond laser

期刊: JOURNAL OF OPTICS, 2021; 23 (7)

Femtosecond laser-induced optical and structural changes inside transparent materials are crucial to ultrafast laser micromachining. In this work, on-......
