What is an optical switch?
Optical switches can be divided into two main categories: mechanical and non-mechanical. Mechanical optical switches rely on the movement of optical fibers or optical components to change the optical path; non-mechanical optical switches rely on electro-optic, acousto-optic, or thermo-optic effects to change the refractive index of the waveguide, thereby altering the optical path. The structure and working principles of these two types of optical switches are described below.
