Optical fibers are made from either glass or plastic. Most are roughly the diameter of a human hair, and they may be many miles long. Light is transmitted along the center of the fiber from one end...

As bit rates increase to meet expanding demand, systems have become increasingly sensitive to polarization-related impairments. These include polarization mode dispersion (PMD) in optical fibers,...

Just as an electronic connector provides a pluggable connection between electronic circuits, a fiber optic connector provides an optical one. The goal is joining a fiber to a transmitter, receiver or...

Spectral selection is a powerful tool that enhances conventional imaging tremendously. Most imaging systems, including the human eye, are designed to image light over a broad range of the spectrum....

Vertical Cavity Surface Emitting Lasers (VCSELs) revolutionized communications systems in the 1990s. As the technology improved, VCSELs began to be employed in sensing applications because of the...

Two- and three-dimensional photonics arrays are commonly used for coupling light in photonic integrated circuits (PICs). With increasing demand for ultralow-loss transmission in applications such as...

Diouf discusses his team’s investigations of the self-healing (self-reconstituting) capabilities of the space-time light sheet when it interacts with a partially transparent object,...

Plasmonics, or the investigation and manipulation of electron oscillations along metal–dielectric interfaces, is an emerging technology with great innovation potential. Biophotonic sensing,...

Noise generated within an optical communications system link that has both internal (dark current) and external (background noise, or noise in signal) components.

An optical coupling device that uses light to bridge the gap between incompatible wire communications systems. It contains an input amplifier, a light-emitting diode, a photodiode and an output...

A laser crystal, also known as an active medium or gain medium, is a solid-state material used in the construction of lasers. The primary function of the laser crystal is to amplify light by...

The unwanted and unpredictable fluctuations that distort a received signal and hence tend to obscure the desired message. Noise disturbances, which may be generated in the devices of a communications...
