Innovative Developments of Optical Fiber using Multiplexing/Demultiplexing
Abstract: AbstractAs of late, numerous exploration works have been centered around the fiber optic gadgets for optical correspondence frameworks. One of the principle hobbies is on the optical intensifiers to support a powerless flag in the correspondence frameworks. Keeping in mind the end goal to conquer the confinements forced by electrical recovery, a method for optical intensification was looked for. The contending innovation developed: the first was Raman enhancement. One reason …

Non-linear Photonic Crystals and their Applications: A Review
Abstract: The nonlinear photonic crystals (NLPCs) are periodic material structures in which nonlinear materials are used for photonic structure formation. In nonlinear photonic crystals, the optical response mainly depends on the intensity of the light beam that propagates through the photonic crystal. These structures show new optical properties with improved or enhanced or new functionalities that cannot be observed in linear photonic crystals. In addition to this, using nonlinear materials in …

A Review on the Light Transmission Behaviour of Concrete Using Plexiglass Fibres
Abstract: The transparent behaviour of concrete can be improved using optical fibres which enable the transmission of light into the concrete, by decreasing the energy consumption and carbon footprint, to provide a sustainable living environment. To investigate the effect of the usage of plastic optical fibres, different blocks are cast and tested for light transmission properties. The rates of usage of plastic optical fibres are varied under the same loading conditions …

Integrated Analysis of Stress Patterns in Transparent Polycarbonate Specimens: A Comparative Study between Photoelasticity and FEA Simulation for Compact Circular Testing
Abstract: Photoelasticity stands as a robust experimental technique within the realms of mechanics and materials science, offering a means to visually assess and analyze stress distribution within materials possessing transparency or translucency. This method, a non-destructive testing approach, involves the visualization of stress on a model subjected to a load, leveraging the unique property of materials known as birefringence or double refraction. The procedure entails the careful selection of a suitable …

Asymmetrical Light Propagation in 2D Photonic Crystal Structure
Abstract: In this work, using Plane Wave Expansion (PWE) and two-dimensional Finite Difference Time Domain (2D-FDTD) methods, we design a structure that shows the high asymmetry in propagation of light. Structure is based on two-dimensional Photonic Crystal (2D-PC) consisting of square lattice (39 X 39) of infinitely long circular rods of refractive index 2.9 in the background of refractive index 1. Radius of rods is 0.15a, where a is the lattice …

Using FEA Simulation and Photoelasticity Techniques to observe Integrated Stress Pattern for Transparent Polycarbonate Rectangular Specimen having Arc Feature
Abstract: In the fields of mechanics and materials science, photoelasticity is a reliable experimental method that provides a visual evaluation and analysis of the distribution of stress in materials that are transparent or translucent. This non-destructive testing technique uses the special property of materials known as birefringence, or double refraction, to visualise stress on a model under load. The process involves building a physical model that mimics real-world structures, applying mechanical …

Polymer-Integrated Smart Biomedical Waste Management System Using AI and Sensor-Based Segregation
Abstract: Biomedical waste, which comes from healthcare facilities like hospitals, clinics, and labs, includes both infectious and non-infectious materials. This can range from sharps and pathological waste to pharmaceutical leftovers and general medical trash. If this waste isn't handled, sorted, and disposed of properly, it can pose serious contamination risks, leading to infections, workplace hazards, environmental damage, and public health emergencies. Traditional biomedical waste management often relies on manual sorting, which …
