Intraband wraps up Wisconsin-Madison licence

Infrared laser manufacturer Intraband was spun out in 2007 and is aiming to deliver products for purposes including medical diagnostics and environmental monitoring.

Intraband, a US-based infrared laser manufacturer spun out of University of Wisconsin-Madison, secured an additional licence on Monday from the university’s tech transfer unit, Wisconsin Alumni Research Foundation (Warf).

The patents relate to an approach for emitting optical power at mid-range infrared wavelengths from a single chip built with metalorganic chemical vapour deposition, a semiconductor production technique that offers high throughput.

Intraband plans to use the technology in quantum cascade laser (QCL) components for purposes such as missile-avoidance systems, medical diagnostics, environmental monitoring and plastics manufacturing.

Founded in 2007, Intraband is focused on new QCLs designed to provide better power, efficiency, reliability and quality than current models. QCLs generally operate in the mid-to-far infrared segment of the electromagnetic spectrum and are capable of generating multiple photons from a single electron.

Intraband is based at UW-Madison’s University Research Park but conducts advanced research at the university’s Reed Center for Photonics. The spinout commercialises research by Dan Botez and Luke Mawst, professors of electrical and computer engineering from the College of Engineering.

Botez and Mawst co-founded Intraband alongside Tom Earles, who leads product development, and Rob Marsland, president of Intraband.

Marsland said: “I am thrilled with how Warf and Intraband have been able to work together on this patent portfolio and look to working with Warf even more in the future as Intraband pursues its commercialisation strategy focused on saving lives and improving the environment.”

Erik Iverson, managing director of Warf, added: “The breakthrough design developed by professors Dan Botez and Luke Mawst enables next-generation quantum cascade lasers that are more reliable and efficient than conventional quantum cascade lasers.

"We are excited to partner with Intraband to advance this technology.”
