Optical fibre sensors are an essential subset of optical fibre technology, designed
specifically for sensing and measuring several physical parameters. These sensors offer …

This paper proposes a photonic crystal fibre (PCF)-based sensor specifically designed to
identify blood components such as haemoglobin, red blood cells (RBCs), white blood cells …

In this study, we theoretically analyze a one-dimensional photonic crystal (1D PC) with a
multidefect structure for potential use in multi-channel optical filtering. Using the transfer …

In this short note, we introduce an optical filter that exhibits independence from unit cells
within a one-dimensional photonic crystal. Our study focuses on a one-dimensional binary …

In this study, we introduce a novel hafnium dioxide (HfO 2) and thin gold layer based
photonic crystal fiber (HfAu-PCF) sensor for refractive index measurement and optimize in …

This study introduces a distinctive entwined photonic crystal fiber (PCF) featuring two distinct
and independent directed mode sections, collectively supporting a total of 112 orbital …

The nonlinear effects and laser-induced optical and thermal damage in optical fibers,
together with the limitations of beam quality and mode-field area, restrict the power scaling …

A dual-ring photonic crystal fiber (PCF) is proposed, which not only supports the stable
transmission of orbital angular momentum (OAM) modes but also deftly mitigates …

Hollow-core anti-resonant fibers (HC-ANF) have the advantages of low scattering loss, wide
bandwidth and simplicity of preparation, but are sensitive to bend, which limits their practical …
