Precision Electro-Optic, Waveguide, and Laser Technologies

Events and Exhibits

We participate in a variety of trade shows and conferences throughout the year. Join us at the following industry-leading events and stop by our booth to learn more about our products.

  • Welcome to DAMOP

    damop-2016Welcome to all DAMOP attendees.  DAMOP, the Division of Atomic and Molecular Optical Physics meeting is underway at the Providence Convention Center in Providence, RI.

    Ben LueyBen Luey, Staff Scientist at Vescent will participate in an Industrial Career Panel and Discussion on Tuesday evening from 6:30 to 9:00 pm in Room 553 AB.  Ben and the other panelist will discuss physics careers in the private sector and laboratory environments. Topics will include research opportunities for physicists in industry, strategies for successfully pursuing industrial jobs, exploring the linkages between private sector and national laboratory research, and advice on how to thrive in these exciting and challenging work environments.  Light refreshments will be served. This event is sponsored by the Forum on Industry and Applied Physics (FIAP). 

    Vescent will be exhibiting its new D2-250 Heterodyne Module for overlapping master and slave lasers and collecting an optical beat note for delivery to a fast detector such as the D2-160.  The electrical beat note can be used as the error signal in an offset phase lock – the easiest way to get an atomically referenced, frequency-agile laser for atomic spectroscopy.  The D2-250 is newly redesigned with kinematic optical mounts to be easier to set up.  It also makes use of rotatable waveplates and polarizing beam splitters to allow a large dynamic range of power inputs making it more versatile than the venerable D2-150.

    We are also introducing two new ICE boards.  ICE, or Integrated Control Electronics, offers the combination of high speed and low noise only available via analog control and an easy to use digital interface (GUI or serial commands).  The new ICE-DC2 offers two channels of current control for driving two diode lasers.  And the ICE-SC1 is a full PI2D loop filter servo that offers an auxiliary servo output for centering the main, high-bandwidth loop, keeping it within its range for extended periods of time.

    See you in Providence!

  • Defense and Commercial Sensing

    SPIE DCS logoVescent Photonics is excited to again be participating in the SPIE Defense and Commercial Sensing Conference in Baltimore, 17-21 April, 2016.  Come see us at Booth 241.

    We are pleased to be presenting two papers.  Our paper No. 9828-7, titled “Laser-based satellite communication systems stabilized by non-mechanical electro-optic scanners,will be in the Airborne Intelligence, Surveillance, Reconnaissance (ISR) Systems and Applications XIII Conference on Monday 18 April at 11:10 am in Convention Center Room 328. 

    Our paper 9832-18, titled “A lightweight and rugged laser radar system enabled by non-mechanical electro-optic beam steerers,”will be in the Laser Radar Technology and Applications XXI Conference on Wednesday 20 April at 8:00 am in Convention Center Room 340.  

    Check the downloads section of our website after the conference to download the Proceedings.

    Vescent will also display products and technology from both of our business lines, including a free-space optical communication (FSO) demonstration based on Vescent’s unique liquid crystal waveguide technology. The engine for establishing & maintaining the communication link is the SEEOR (Steerable Electro-Evanescent Optical Refractor), our non-mechanical beam-steering product.

    The SEEOR takes advantage of the extraordinarily large electro-optic effect of liquid crystal materials (>105 times that of LiNbO­3) to create a tunable Snell’s Law prism which will controllably refract a laser beam over a Field of View of more than 30° x 5°. It is truly analog, allowing for raster scanning, tracking, zooming, and point & hold control. The FSO depends on the raster scanning to find and establish an optical link and then the tracking to keep the data flowing.  Fast analog pointing feedback and control to the SEEOR allows the FSO device to create and maintain a robust, high-speed, multiplexed data link.

    Also on display will be Vescent’s D2 and ICE product lines – two strategies for driving and controlling semiconductor lasers.  The D2 products allows for hands-on analog adjustment of control parameters while ICE allows for much easier digital control and board-level OEM implementation.  Both D2 and ICE drive & control the lasers using analog circuits for high speed and low noise.  The two product lines share the same overall performance, but allow different implementation strategies.

    We look forward to seeing you in Baltimore!

  • Photonics West
