Photonic Crystal Improves IR Sensor Performance

Facebook X LinkedIn Email
Demonstration device employs dots-in-a-well architecture.

Daniel S. Burgess

Scientists at the University of New Mexico in Albuquerque and at California Institute of Technology in Pasadena have reported that the addition of a two-dimensional hexagonal photonic crystal to a quantum dots-in-a-well infrared photodetector improves its performance by more than an order of magnitude. They note that the method should be suitable for use with a variety of IR sensors with applications in reconnaissance and rescue, medical diagnostics and firefighting. Sanjay Krishna, an assistant professor of electrical and computer engineering at the university’s Center for High Tech...Read full article
