mid-ir leds can help pollution

You don’t make money sitting in traffic

Technology innovations advance at breakneck speed all around us, with widgets and chips for every device on the planet becoming nearly obsolete shortly after going to market. So it is tempting to want to bypass the technology Autobahn and stay on roads you are most familiar with despite the congestion. But as Wayne Huizenga, founder of three Fortune 500 companies, and six NYSE listed companies reminds us, “you don’t make money sitting in traffic.”

Terahertz Device Corporation’s regulated pulse driver for the mid-infrared QuiC SLED

Salt Lake City, Utah (April 2015)Terahertz Device Corporation announces a current-regulated pulse driver (RPD) for its QuiC SLED mid-infrared LEDs. The driver’s burst mode delivers short pulses of high current for maximum LED brightness without overheating, ideal for time-gating and peak detection where maximum brightness is crucial to performance. A quasi-continuous wave (qCW) mode generates a low-amplitude pulse train at 50% duty cycle, suited for time-averaged power detection by maximizing emitted photons per period. Lock-in amplifiers likewise benefit under qCW mode.

The RPD cuts engineering time and expenses, ensuring the QuiC SLED works out of the box. Matched to the QuiC SLED, the RPD protects the LED and delivers a repeatable current and brightness. The active feedback regulation provides a consistent drive current under variable load conditions with changing device temperatures and between devices.

The QuiC SLED developer kit combines the RPD with the PDQ photodiode amplifier, mounts, and optics.

Terahertz Device Corporation announces the first mid-infrared LEDs of its new QuiC SLED™ product line

Salt Lake City — May 2014 — Terahertz Device Corporation has announced availability for the first devices of its QuiC SLED™ product line. The LEDs emit 4.25 µm wavelength light, with peak powers above 2 milliwatts. This new technology brings bright, fast-switching lights to the mid-wave infrared (MWIR) atmospheric window, and the emission peak of this first product overlaps the carbon dioxide absorption line. These lights enable and enhance applications in chemical and gas sensing, thermal imaging, night vision, spectroscopy, biophotonics, medical sensing, and communications.

“These first devices easily push past the milliwatt barrier for mid-infrared LEDs,” says CEO Mark Miller. “Truly frontier devices, they validate our LED technology. The QuiC SLED™ technologies position us to define the envelope for LED wavelength, power, and performance, throughout the mid-infrared spectrum.”

The devices are quantum interband-cascade superlattice light-emitting diodes, and the key technologies behind the QuiC SLED™product line cover mid-infrared wavelengths from about 3 µm to 15 µm. The company is developing and introducing devices across the mid-infrared spectrum, including many standard and custom wavelengths for which no other LED solutions are available. Compared to thermal, blackbody emitters, these LEDs have modulation frequencies more than a million times faster and do not require optical filter assemblies to select wavelengths. Compared to quantum cascade lasers and interband cascade lasers, these LEDs have broader lines to cover larger spectral ranges, they ensure eye-safe implementations, and they bring device and system cost savings.
