Huntsville, AL – EngeniusMicro is pleased to announce that it has been awarded a Small Business Innovation Research (SBIR) Phase II contract from the U.S. Army to develop a microelectromechanical systems (MEMS) optical cavity with anomalous dispersion (MOCAD). The goal of this project is to create a compact and robust implementation of a micro optical cavity with anomalous dispersive gas media and develop a millimeter-scale inertial sensor to utilize this technology. 

Anomalous dispersion media has the potential to greatly enhance the sensitivity of optical inertial sensors. However, the signal extinction is a major issue that needs to be addressed. The previous efforts of [Company Name] demonstrated critical components and processes to align and assemble microscale optical components to exploit the anomalous dispersion effect. This Phase II proposal aims to overcome this limitation by developing a passively-aligned microfabricated cavity, eliminating much of the complexity inhibiting production and manufacturability. 

“This SBIR award is a significant milestone for our company and we are excited to continue our work on developing this cutting-edge technology,” said Dr. Brian English, Principle Investigator of the MOCAD project. “The integration of a microoptical cavity with dispersive media will enable shorter path lengths and less attenuation in the optical path, which will have a significant impact on the sensitivity and performance of inertial sensors.” 

The technologies leveraged to accomplish this include spherical and 45-degree micromirrors, kinematic constraints using V-grooves, and precise bonding at the die level. The dispersive media cell design will leverage dispensers that eliminate the need for highly specialized high-vacuum equipment and ensure the quality of the media cell.
