Mid-IR LEDs to compete with lasers?

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.

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.”

Lasers versus LEDs

Lasers versus LEDs – The Debate

The Seventh Sense Blog recently published a blog post on the Sensors Magazine online site (click here for the full article). 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. Lasers versus LEDs

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!

Climate change, global warming, and LEDs

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 dioxide in trapping heat in the atmosphere.

We look forward to doing our part in global warming and climate change.

You are welcome.
