Team members from IRG have collaborated with researchers at MIT, University of Delaware, Clemson University, and University of Central Florida on the development of mid-infrared (mid-IR) photonic materials and devices fabricated on silicon for on-chip sensing applications, as discussed in a recent review article in Science and Technology of Advanced Materials. These on-chip sensor systems incorporate chalcogenide glasses in waveguides and micro-resonators.

“Integrated photonics are poised to play a prime role in the emerging field of on-chip biological and chemical sensing.”

A recent market report by WinterGreen Research states that the mid-IR sensor market is anticipated to reach $7 billion by 2019.

Applications for Mid-IR sensors include homeland security, military communications, infrared countermeasures, chemical warfare agent detection, explosives detection, medical diagnostics, imaging and industrial process controls, fire detection and remote gas leak detection, pollution monitoring, and real-time combustion controls.

The journal article authors assert that “integrated, on-chip photonic devices present a compelling solution to several technical challenges due to their small footprint, low fabrication cost and immunity to electromagnetic interference. Their versatility is showcased by applications that range from high-speed telecommunications to on-chip optical interconnects to imaging and photovoltaics. More importantly, integrated photonics are also poised to play a prime role in the emerging field of on-chip biological and chemical sensing.”
