Before we discuss a fused coupler, we must discuss light polarization. Light moves in different directions when no path is defined and nothing is defined. When the light goes in multiple directions, it isn’t polarized; whereas, when light is controlled and goes into a single desired direction, it’s polarized. The movement of light into a
Optical noise is common in optical systems such as fiber amplifiers and fiber laser systems because both include the amplification process. Amplification of optical signals generates optical noise through the spontaneous emission process. The process of spontaneous emission occurs when the light produced by the spontaneous decay of excited erbium ions is coupled to the
A 980nm inline polarizer is an optical component that is used to selectively reflect or transmit light of a particular polarization or convert non-polarized light into polarized light. The most common use for a 980nm inline polarizer is in devices that require high levels of light intensity, such as lasers and fiber-optic communication systems. What
