Some of the questions that arise about the optical fibers (OF) are: What is the structure of an optical fiber? How does light propagate along a fiber? What materials are used to make optical fibers? What is the process of making the OF? What is […]
Resistors in Circuits There are three things, in Ohm’s Law Resistance Voltage Current In this equation if I increases then R will decrease. It means the result of product remain same i.e., V. If voltage remain constant between two points it means it is balanced […]
Introduction of Magnetic Hysteresis Loop To understand this topic first of all we have to understand the basic concept. Like what is magnetic flux density and magnetic field intensity right? Also, permeability plays an important role in magnetism. Here, two things are by which I […]
Concept of Classical theory of Ferromagnetic Material is explained here with the supporting physical concepts (SPC’s) This concept will be helpful to understand the B H Curve explanation.
Introduction to Semiconductor LASER In this video tutorial of semiconductor LASER the following points which given below are explained. The GaAs is responsible for the optical properties when electron and holes recombines in depletion region. As you know in Si/Ge semiconductor material when this recombination […]
Attenuation losses in Optical Fibers An optical fiber is made of either glass or plastic material. The refractive index of the material plays an important role in the transmission of an optical signal used further in communications. This signal travel inside the core of an […]
