What is the working principle of a beam splitter s optical metering grating
The basic principle is straightforward: light hits a specially coated surface, and that coating is engineered to reflect some of the light while letting the rest pass through. By adjusting the coating's material and thickness, manufacturers control exactly how much light goes each. 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. a laser beam) into two (or sometimes more) beams, which may or may not have the same optical power (radiant flux). These tools can split both laser and regular light. One portion passes through the device while the other reflects off it, and the ratio between the two can be controlled by design.

Working principle of WSS optical module
A WSS comprises a switching array that operates on light that has been dispersed in wavelength without the requirement that the dispersed light be physically demultiplexed into separate ports. This is termed a 'disperse and switch' configuration. Wavelength selective switching components are used in WDM optical communications networks to route (switch) signals between optical fibres on a per-wavelength basis.
