The high levels of integration and widespread use of MEMS structures (in many cases) is enabling new electro-optical devices that would be difficult or impossible to implement otherwise. These can function as RF/microwave devices, optical devices, sophisticated sensors, medical devices, and advanced yet tiny test-and-measurement systems.
Tests are underway on an optically based, multi-wavelength system that allows for fast, accurate, noninvasive diagnosis of rheumatoid arthritis.
Conventional calibration of “breathalyzers” is difficult and error-prone. A laser-driven optical-electronic system implements a radically different and more-precise approach to this metrology challenge.
Using an innovative, no-loss technique for combining smaller optical-MEMS arrays, researchers built and fully evaluated an electronically controlled, 240-input × 240-output, all-optical switching matrix.
A research team replaced the conventional spark-plug ignition of the gasoline engine with a laser-based system, yielding improvements in engine performance and reduced emissions.
