Emerging Mid-IR LEDs are competing with lasers in health & environmental sensing, according to Dr. Mark Miller, as featured in the latest edition of Laser Focus World magazine.
LEDs emerge in environmental and health sensing markets
The voracious appetite of the internet-of-things for high-volume, inexpensive optical sensor nodes favors mid-infrared LEDs over lasers for many unmet environmental and health sensing needs. Quantum interband cascade superlattice light emitting diodes (QuiC SLEDs) bring the wavelengths and performance to make these billion-node applications possible.
In this article, there is a complete review of the evolution of mid-IR LEDs, quantum engineering, and a comparison of the QuiC SLED™ to other alloy LEDs, thermal heat sources, and laser diodes.
