The Goos-Hänchen effect describes a small but measurable lateral shift of an optical beam when it reflects or refracts at an interface, deviating from the path predicted by geometrical optics. This ...

The success of infrared systems depends on the performance of their optical coatings. While materials like germanium and silicon transmit well, they suffer from high reflection losses. Engineered coat ...

Fibre optics and optical communications is the use of thin strands of glass for sending information encoded into light over long distances. Total internal reflection prevents light inserted into one ...

This is the first part in a series on the basic principles of fiber optic communication. Have you ever wondered how the data we transmit through the internet is able to travel thousands of miles ...

The basics of fiber optic cables and bundles and how they can be used to collect and direct light are discussed in ‘An Introduction to a Spectrometer: Fiber Optic Bundles’. This article will discuss ...
