I recently mentioned Genia Photonics, (GP),and the recent agreement it has entered into with In-Q-Tel in my end of the year post. I noted that aside from the collective "buzz", that is currently going on regarding CMOS, solid state THz, the news about GP's, new very powerful and very highly sensitive new THz product, was the most interesting THz related story this year in my opinion.
I also mentioned that I had tried to make contact with GP, to learn more to share with you here, but that I had not had any luck. Writing about GP earlier this week peaked my interest anew, and I revisited their web-page. http://www.geniaphotonics.com/ Let me share with you what I found.
Founded in 2009 by the merger of Optav Solutions and FG2 Tech, Genia Photonics Inc. webpage states it is an innovative company specializing in high-speed picosecond fiber-based lasers and spectroscopic measurement systems. Centered around it's patented fiber laser technology, Genia’s compact, easy to use and controlled via software systems is claimed to change the methodology for various applications in biomedical, industrial as well as defense and security. Dr. Gonthier and Dr. Villeneuve boast together over 35 years of experience in transferring innovative R & D technology into profitable commercial products.
What I found to be really informative and helpful in substantiating GP's claims were articles found under the news tab, on the homepage. (Note that you can't access these pages without first signing your name & email address, but if you do access is immediate).
I found two articles to be of much interest to me, (the first of which I will provide you with a lay-persons, non-technical review). The first is a reprint of an article In-Q-Tel, published in April of 2012, about GP, which is titled "Standoff Explosive Detection".
In-Q-Tel, in this paper substantiates GP's claims, as IQT, notes that GP has a "technical advantage".
'Genia Photoics offers fiber-based laser solutions that leverage the benefits of fiber, such as durability, robustness, small size, lower total cost and increased reliability, /The lasers are all software controlled which through the embedded electronics permits all the laser''s characteristic parameters [wavelength, pulse width, output power, and tuning speed] to be easily controlled. The wide wavelength tuning range and the fast tuning speed of the laser are key enablers for standoff explosive detection, allowing greater coverage for a given time interval or a reduction of the scanning time interval for a specific area."
The article is 3 pages in length and notes a number of other technical advantages the GP fiber-based laser. The system allows for nonlinear spectroscopy as well as mid-IR spectroscopy. The detailed article concludes by noting that:
"The versatile synchronized laser system supports various standoff detection schemes. It offers many desired features and capabilities such as wavelength tuning, pulse width variation, output power control, and repetition rate variation. The ability of wavelengths to be swept at a very fast rate enables a specific area to be scanned in a much shorter time interval. And, since the wavelength and repetition rate are associated, the need for a spectrometer at the receiving end is eliminated. Multiple detectors can then be economically deployed to capture more reflected light for a better analysis. Moreover, since all parameters are controlled electronically via software, it is possible to combine different detection techniques [bulk and trace simultaneously] in order to obtain a full detection of the targeted sample."
The second article I would recommend readers read is entitled "How Tunable Lasers are Revolutionizing Spectroscopy", which was authored internally at GP. It also more fully describes the revolutionary laser GP has developed for use in THz.
I once again encourage readers to review these articles in their entirety on the GP webpage, which is linked above.
