Join the Terahertz Device Corp team at this year’s Sensors Expo 2017.
Booth #1621
DATES: Wednesday – Thursday, June 28-29, 2017
We will be showcasing our QuiC SLED™ CO2 sensor and detector, and can answer questions about your custom mid-IR LED needs including sensing at various wavelengths from 3µm – 12µm. These wavelengths are great for sensing CO2, CO, ethanol, NH3, methane, glucose, and more.
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 is the leader in Mid-infrared LED advancements and will help you avoid all the “traffic delays” to grow your business successfully. Our QuiC SLED™ (quantum cascade superlattice LEDs) enable and enhance your applications in chemical and gas sensing, thermal imaging, night vision, spectroscopy, biophotonics, medical sensing, and communications.
Is climate change in your mission? Are you in global warming regulation and compliance?
Do you want to save money with more efficient CO2 monitoring in smart building and smart home applications?
Are you in oil and gas production, manufacturing, and distribution with needs in widespread methane and other compound sensing?
Would you like to be the first in the wearable device markets to monitor blood glucose and other biomarkers in skin?
With so many applications, our technology can get you out of traffic and to the next level; because as Wayne Huizenga also shares: “Some people dream of success, while other people get up every morning and make it happen.”
Let’s connect today!

The Seventh Sense Blog recently published a blog post on the Sensors Magazine online site. The unknown author referred to as “MD” professes that “Light emitting diodes (LEDs) are probably the most chronicled electronic components of all time, the ones finding more applications by the minute, and the fastest developing…” He (or she) goes on to compare the laser and the LED, featuring the commonalities as well as the differences between laser technology and LED’s.
Some of the highlights of this article include:
“A typical ILD…operates like an LED in that light emission depends on current flow through a PN junction, however it differs in its ability to contain and focus light and its lower-power capabilities.”
“Light emitting diodes (LEDs) are much simpler than laser diodes and share several attributes including their semiconductor origins and the ability to act as a light source. LEDs are also, in some ways, more versatile. For one thing, LEDs handle a wider range of mainstream applications and most people are more knowledgeable when it comes to LEDs as opposed to laser diodes.”
“A semiconductor light source, LEDs are available in three types: low power (2 mA to 20 mA), mid power (100 mA to 1W), and high-power (1W to 3W and higher on the horizon). Wavelengths do not extend to the reaches of laser diodes; LEDs span from less than 400 nm (ultra violet) to around 760 nm (infrared).”
NOTE: We know that LED’s actually span as high as 15 µm (or 15000 nm) with our own mid-infrared LED technology. But we can’t fault the author for not knowing what he doesn’t know, can we?
There is a great comparison chart as well that is worth a review.
To sum up, we enjoy the optimism this author has about the future of LED’s. We look forward to the next rendition of this article after he discovers how far LED’s have come in the last couple years!

Can mid-infrared LEDs impact global warming through Internet of Things sensing for methane & CO2?
We think so!
After reviewing this article written by Beatrice Gitau of the Christian Science Monitor about methane gas leaking from the ocean floor, we got to thinking “What if our mid-infrared LEDs, or QuiC SLEDs as we call them, could impact global warming by early detection of methane and carbon dioxide gases by just a few percent? Would that matter?”
Here is a quote from the article that I found interesting:
In 2013, methane accounted for about 10 percent of all US greenhouse gas emissions from human activities according to EPA. Although there’s much less methane in the atmosphere, the gas is 23 times more potent than carbon dioxidein trapping heat in the atmosphere.
We look forward to doing our part in global warming and climate change.
You are welcome.

For immediate release
Salt Lake City, Utah – April 2015 – Terahertz Device Corporation announces its photodiode amplifier (PDA) for the PDQ (photodiode QuiC) of its QuiC SLED™ product line. The amplifier matches the PDQ impedance, producing a photodetector fast enough to follow a QuiC SLED™ mid-infrared LED signal.
The PDQ operates at room temperature, reducing cryogenic system needs. New gas sensing and communication applications open in the mid-infrared with a PDQ-QuiC SLED™ pair configured for high-speed and low-power. The PDA cuts engineering time and expenses, ensuring the PDQ works out of the box.
The QuiC SLED™ developer kit combines the regulated pulse driver with the PDQ photodiode amplifier, mounts, and optics.

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.
