Waveguides are used in everything from the transmission of sound waves to optical communications. Every application that uses a waveguide requires a waveguide with a specifically designed structure, as this it what determines the waveguide’s function.

Spectroscopy is a broad technique, with many different types available to researchers. Each type of spectroscopy measures different bandwidths of radiation, and can be used to determine different chemical and material properties. In this article, we look at fluorescence spectroscopy.

Optical imaging is a technology which explains the characteristics of infrared, ultraviolet and visible light. It is a non-invasive technique which uses non-ionizing radiation in order to obtain images of tissues and organs. These images can be used by clinicians in order to diagnose and prevent diseases.
Spontaneous parametric down conversion is as an optical quantum process in which an incident photon is converted into pairs of entangled photons by a non-linear medium.
Attenuation is defined as the gradual loss in the intensity of any kind of flux when it passes through a medium.
In the field of optics, optical path length or optical distance is the product of the geometric length of the path light follows through a system, and the index of refraction of the medium through which it propagates.
Optical isolators are optical elements which allow light to propagate in only one direction. The propagation of light in one single direction is required in order to prevent optical back scattering or feedback which often leads to noise in many applications.
Four-wave mixing (FWM) is a non-linear optical process where two other waves are produced by the interaction of two wavelengths. Four-wave mixing can take place in any kind of material.
