- Vescent to show non-mechanical optical communication link at Photonics West
Golden, CO (14 Feb, 2016) Vescent Photonics will unveil a free-space optical communication (FSO) demonstration based on its unique liquid crystal waveguide technology. A completely non-mechanical, live optical link with multiplexed data transmission will be on display. The engine for establishing & maintaining the communication link is the SEEOR (Steerable Electro-Evanescent Optical Refractor), the 2015 Prism Award-nominated non-mechanical beam steering device.
Dr. Scott Davis, VP of Technology at Vescent explains, “The SEEOR takes advantage of the extraordinarily large electro-optic effect of liquid crystals to create a tunable Snell’s Law prism which controllably refracts a laser beam over a large Field of View.” The SEEOR is truly analog, allowing for raster scanning, tracking, zooming, and point & hold – all essential for the FSO link to function. Davis continues, “We expect the FSO to be deployed in the secure and satellite communications fields while the SEEOR itself will prove to be a key enabler to non-mechanical LIDAR and will address high-volume commercial markets such as automated driving, inspection & handling robotics, and gaming.”
About Vescent Photonics: Vescent Photonics, Inc., a privately held company, was founded in 2002 to develop and manufacture technologies in waveguide, electro-optics, tunable lasers, and electronics for precision laser control. Staff experience as researchers at the University of Colorado (JILA), NIST, the Colorado School of Mines, and the University of California at Berkeley has allowed us to become a leader in liquid crystal waveguide technology. The company is wholly owned by the original founders.
- Gravitational Wave Detection Confirmed
Confirming a prediction of Albert Einstein’s from a hundred years ago, scientist from LIGO (Laser Interferometer Gravitational-wave Observatory) have confirmed the existence of gravitational waves.
Two multi-kilometer interferometers in Washington and Louisiana states made coincident measurements confirming the detection of the gravitational wave on 14 September 2015. An abundance of caution led the scientist to delay official announcement of the discovery until a press conference on 11 February 2016.
Quoting from the Caltech website – a leading institution coordinating LIGO: In an “event about 3 times the mass of the sun was converted into gravitational waves in a fraction of a second — with a peak power output about 50 times that of the whole visible universe.”
And on the MIT website, Rainer Weiss, a professor emeritus of physics at MIT, the other leading institution behind LIGO, says, “It’s a spectacular signal. It’s a signal many of us have wanted to observe since the time LIGO was proposed.” Prof. Weiss continued, “Einstein is right in a regime where his theory has never been tested before.”
The paper discussing the observation has been accepted by the Physical Review Letters.
Congratulations to the entire LIGO team! LIGO is an NSF-funded program.
- Vescent is 2015 Prism Award Finalist
Vescent Photonics is proud to announce that we have been selected as a finalist for the 2015 Prism Awards for Photonics Innovation. The Prism Awards, sponsored by SPIE, honor the best new photonics products on the market. We have been nominated to the Optics and Components category for our SEEOR laser scanner.
The SEEOR (Steerable Electro-Evanescent Optical Refractor) is a completely non-mechanical beam steering device which features low SWaP and will allow the laser to interrogate a 35×8° field of regard. Unlike resonant MEMS scanners, the SEEOR will allow you to not only rapidly scan a field, but will also allow zooming to specific portions of the field, point and hold capability, and tracking. With no moving parts, it is not subject to inertial effects and the liquid crystal-based technology does not require the high power consumption of ao modulators.
See you in San Francisco!
- Vescent Staff Scientist Profiled by Denver Philharmonic
That’s Vescent’s very own Senior Scientist Ben Luey being profiled on the Denver Philharmonic’s web page, the Buzz. Ben has been with Vescent Photonics for 9 years and he has been playing the viola for the Denver Philharmonic all this time. We are proud that Ben has found time to lead our Electrical and Optical Engineering teams through many successful product launches and SBIR grants as well as to enhance the Denver cultural environment. Thanks, Ben.
- Vescent Photonics Has Moved
Vescent Photonics is proud to announce that we have moved our operations into a newer, larger facility. After bursting at the seams for a number of years, we have increased our square footage by roughly a factor of 3 to over 10,000 ft2. Our new building has freshly updated workspaces, including an abundance of power, light, and connectivity. It also boasts of expanded labs and production floor space, a stock room, and a 2,000 ft2 class 10,000 clean room.
Our new home office is located at:
14998 W. 6th Ave.
Golden, CO 80401
We’d be pleased to host a visit if you’d like to see the new building.
We did not change any of our phone lines or internet connectivity.

- Laser Fusion Achieved at NIF
Scientists at the National Ignition Facility (NIF) in Livermore, CA report that for the first time a laser-initiated plasma has produced more energy than was put into it. Although the total amount of energy in the laser pulse was greater than that released, this is considered to be a significant step as greater than unity gain was achieved for the light that actually struck the target. The group published their findings in Nature, the International Weekly Journal of Science. News outlets, including NPR, have reported the story.
