What's the difference between 2D MEMS and 3D MEMS Switches?

MEMS (Microelectromechanical Systems) optical switches are devices that use microelectromechanical systems technology to switch light signals between different optical paths. They are typically used in telecommunications and data center applications.

There are two main types of MEMS optical switches: 2D MEMS optical switches and 3D MEMS optical switches.

2D MEMS optical switches have a simple design and are relatively easy to manufacture. They consist of a glass substrate with a thin layer of silicon on top. The silicon layer is patterned with a series of mirrors, which are actuated by electrostatic forces. When an electrical signal is applied to the mirrors, they rotate and reflect the light to the desired output port.

2D MEMS optical switches are available in a variety of configurations, including 1x2, 1x4, and 1x8. They can also be used to switch between multiple wavelengths of light.

3D MEMS optical switches are more complex than 2D MEMS optical switches, but they offer a number of advantages. 3D MEMS optical switches have a smaller footprint and are less power-hungry than 2D MEMS optical switches. They also offer lower insertion loss and crosstalk.
