It has recently been argued that the geometric-optics mean path length of rays inside a refractive object under Lambertian illumination is independent of the scattering strength of the medium [Savo et al., Science 358, 765 (2017)]. We here show that

The diffraction beam characteristics of tapered-platform fiber are demonstrated by theoretical analysis and experimental measurement. The tapered-platform fiber is designed and fabricated. Based on light ray theory, the Gauss beam lens conversion mod

We designed and manufactured a novel annular-core hollow beam fiber which could directly yield ring light with a central dark spot inside the beam employing MCVD technique and a custom-made fiber drawing tower. The tapered fiber zone geometric shapes

The improved definitions for mode-field radius and divergence half-angle of optical fiber with an arbitrary index profile are proposed in this paper, and their simple relationship as well as their relations to the second moment and differential opera

We have developed a nondestructive method to determine the azimuth angle orientation of a microstructured optical fiber (MOF). In our approach, incoherent light is used to illuminate the MOF and its side image is recorded. We defined a characteristic

The mode theory is the main way to study the propagation characteristics of light in fiber so far, but it is not suitable for analysis of light in duct. By using ray-tracing method, the rotary propagation characteristics of light in multimode-single

A $1 \times N$ fiber coupler based on a single-polyhedral gradient-index lens (p-GRIN) is proposed. The entrance end of the p-GRIN has polyhedral convex cone shape with N surfaces and the exit end has a flat surface. When light from a single-core opt

The refractive index profile of a non-bending small-core single-mode fiber was first reconstructed from the measured guided mode intensity profile and its spatial derivatives. By combining a rotating diffuser with a coherent laser source, the resulti
