Introduction
MEMS optical switches are a type of optical switch that uses microelectromechanical systems (MEMS) to control the flow of light. MEMS are miniature mechanical devices that can be fabricated on a semiconductor substrate using a variety of techniques, including photolithography, etching, and deposition.
MEMS optical switches offer a number of advantages over other types of optical switches, including:
Small size and weight: MEMS optical switches are typically much smaller and lighter than other types of optical switches, making them ideal for applications where space and weight are limited.
Low power consumption: MEMS optical switches typically consume much less power than other types of optical switches, making them more energy efficient.
High reliability: MEMS optical switches are typically very reliable, with failure rates of less than 1%.
Types of MEMS Optical Switches
There are two main types of MEMS optical switches:
Rotary MEMS optical switches: Rotary MEMS optical switches use a rotating mirror to control the flow of light.
Tilting MEMS optical switches: Tilting MEMS optical switches use a tilting mirror to control the flow of light.
