Passive Beam Splitter Construction

Beam splitters are classified by construction (plate, cube, pellicle, polka dot) and by function (standard, non-polarizing, polarizing, dichroic). Construction determines ghosting, damage threshold, and form factor. A splitter is not a filter like a wavelength division multiplexer (WDM). Rarely, there can be two inputs to provide potential redundancy of route. Light power goes in and light power coming out. A beam splitter or beamsplitter is an optical device that splits a beam of light into a transmitted and a reflected beam. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications. The tutorial has the following parts: Figure 1: A 2-by-2 fiber coupler.
