What is a MEMS Optical Switch?

The MEMS optical switch is to engrave a number of tiny mirrors on the silicon crystal. Through the action of electrostatic force or electromagnetic force, the micro-mirror array is rotated, thereby changing the propagation direction of the input light to realize the function of on-off of the optical path. The MEMS optical switch switches the light wave routing through external control information and the corresponding high and low levels to control whether the internal micro mirror is lifted or not.

Advantages of MEMS Optical Switches

MEMS optical switches can realize comprehensive remote control of all-optical networks, and have the main advantages of integration, low power consumption and low cost. MEMS optical switches have the advantages of low insertion loss, low crosstalk, low polarization sensitivity, high extinction ratio of mechanical optical switches and high switching speed, small size, and easy large-scale integration of waveguide switches.

MEMS 1×N-Port Optical Switch Structure

A 1×N-port optical switch based on MEMS technology, which includes a MEMS micromirror, a collimating lens and a multi-fiber pin. The MEMS micromirror is usually mounted on a TO tube holder, and then the collimating lens and the TO tube holder are assembled into a component through the TO tube cap. Finally, in the active debugging state, the multi-fiber pin is aligned with the aforementioned component and assembled. fixed together.

MEMS optical switch can be applied in the field

MEMS optical switches and their arrays have a wide range of applications in existing optical communications. Its application scope mainly includes: protection switching system of optical network, light source control in optical fiber testing, real-time monitoring system of network performance, testing of optical components, switching core for building OXC equipment, optical add/drop multiplexing, optical testing, optical sensor system, etc.

Principle of MEMS Optical Switch

The principle of the MEMS optical switch is very simple. When the light is exchanged, the angle of the MEMS micromirror is moved or changed through the driving of electrostatic force or magnetic power, and the input light is switched to the different output ends of the optical switch to realize the switching and on-off of the optical path. .

Frequently Asked Question

Do you have any question?

MEMS (Micro-Electro-Mechanical System) refers to a mass-produced micro-device or system that integrates micro-machines, micro-actuators, signal processing and control circuits. The preparation process of micro-mechanical structures includes photolithography, ion beam Etching, chemical etching, wafer bonding, etc., while electrodes are prepared on the mechanical structure for electronic control.
