Design and manufacture of high power mid- to long-wave infrared light emitting diodes, both single element and large format arrays. Company members have numerous publications and innovations (patents pending) on these devices.
Design and manufacture of mid-infrared laser diodes, such as interband cascade lasers, vertical cavity surface emitting lasers, and quantum cascade lasers.
We work with partners such as Chip Design Systems and Teledyne Scientific & Imaging to integrate our LEDs and lasers into systems, such as gas sensors, projectors, and medical devices.
We have unparalleled access to cutting-edge user facilities at the University of Iowa, including molecular beam epitaxy, microfabrication, and characterization.
