What Are Optical MEMS and Why Are They Important?
Optical MEMS are a subset of MEMS devices that interact with light rather than electrical signals. These components are typically fabricated using techniques from the semiconductor industry and are capable of manipulating light through microscopic mirrors, gratings, shutters, or waveguides.
What makes them important is their ability to replace traditional bulky optical systems with miniaturized, cost-effective alternatives without compromising performance. They are widely used in:
Optical switching in telecom
Laser beam steering for autonomous vehicles
Optical coherence tomography in healthcare
Consumer electronics like projectors and displays
This convergence of size, speed, and scalability makes Optical MEMS a key enabler for future optical innovation.
Core Drivers Behind Optical MEMS Adoption
The growing need for high-bandwidth communication and precision sensing is significantly driving demand for Optical MEMS. Industries like aerospace, defense, and automotive are leveraging their lightweight and low-power advantages to develop next-generation solutions.
Some of the primary drivers include:
