Fiber Optic Basics

Tutorials

Optical fibers are circular dielectric wave-guides that can transport optical energy and information. They have a central core surrounded by a concentric cladding with slightly lower refractive index.

Introduction to Polarizers

Tutorials

The interaction of light with the atoms or molecules of a material is wavelength dependent. A consequence of this dependence is the resonant interactions related to material dispersion. Another consequence of such resonant interaction is birefringenc...

Polarization in Fiber Optics

Tutorials

A beam of light can be thought of as being composed of two orthogonal electrical vector field components that vary in amplitude and frequency. Polarized light occurs when these two components differ in phase or amplitude. Polarization in optical fibe...

Insights Into Swept-Wavelength Characterization of Passive Fiber-Optic Components

Tutorials

Building a swept-wavelength system requires a tunable laser source, the device under test, power sensors, and a data-acquisition system. The swept-wavelength method for high-resolution wavelength characterization of passive fiber-optic components can...
