TODAY!! Seminar:"Probe and control electronic and nuclear dynamics of small molecules in strong laser fields" by, Dr. Jian Wu 7.14.14/11:00am-12:00pm/ CREOL 102

Abstract:
The near-infrared intense ultrashort laser pulse can be used to probe and control the rich electronic and nuclear dynamics of molecules through the multiphoton process. It is interesting not only for the fundamental molecular physics, but also for the coherent control of the chemical reactions. Experimentally, the electrons and ions ejected from a molecule are measured in coincidence with the cold target recoil ion momentum spectroscopy (COLTRIMS). By using the technique of the coincidence angular streaking, we show that the dynamics of electron localization, especially the instantaneous field-direction and internuclear-distance dependences, can be directly probed and controlled from the diatomic to polyatomic hydrocarbon molecules, which is very recently extended to two-dimension. We show that the vibrational motion of the nuclei can be semi-classically traced and controlled by using two time-delayed ultrashort laser pulses of detuned wavelengths. By controlling the rotational nuclear wavepacket, we impulsively align molecules which can be used to manipulate the spatiotemporal and frequency properties of a properly matched ultrashort laser pulse, e.g., the supercontinuum generation, THz radiation, attraction and repulse of intense filaments, photonic plasma grating, and so on. Our experiments also reveal the electron-nuclear energy sharing in above-threshold multiphoton ionization of molecules.

Save the Date: FPC-MACF joint meeting Sept 25, 2014 at LMMFC

To:  Florida Photonics Cluster members

The next General Members meeting of the Florida Photonics Cluster will be held jointly with the Manufacturers Association of Central Florida (MACF) on September 25, 2014.  The meeting will be held at and hosted by Lockheed Martin Missiles & Fire Control in Orlando.   Please mark your calendars for this meeting, and please invite your company colleagues.  Because of space limitations (90 persons max) and security requirements, only employees of FPC and MACF member organizations will be able to attend this meeting and all attendees must be US citizens, or permanent residents with Green Card.

Final details of the program and LMMFC requirements will be sent with an RSVP request soon, but the program will be our usual agenda, starting at 2:30pm with a brief presentation on the recent DoD RFI on the Institute for Manufacturing Innovation, three talks by LMMFC personnel on their operations, followed by a tour of two of the LMMFC facilities (Fire Control Factory and Optical Components Center), a hosted reception, and a no-host dinner at a local restaurant after the meeting.

Please set aside the afternoon and evening of 9/25/15 for this interesting meeting and networking event. Please also note that attendees should arrive between 1:30pm and NLT 2:00pm (earlier is best) and must complete the check-in process by 2:15pm to attend the meeting; late arrivals will not have a required escort available to go from the security check-in office to the meeting room.  Parking at LMMFC is very limited and carpooling is highly recommended (possible off-site parking areas will be sent with the final agenda).

Thank you for your continuing support of the FPC.  I look forward to seeing you in September.

Best regards,

Jim Pearson

Seminar: "High quality image transport through optical fibers mediated by Anderson localization" by Arash Mafi, Ph.D. / 6/26/14 / 3:00 - 4:00 pm / CREOL 102

Seminar: "High quality image transport through optical fibers mediated by Anderson localization" by Arash Mafi, Ph.D.
Thursday, June 26, 2014 3:00 PM to 4:00 PM
CREOL Room 102

Associate Professor of Electrical Engineering and Computer Science at the University of Wisconsin-Milwaukee

Abstract:
Anderson localization has been a subject of fascination and intense research for more than fifty years. It is highly desirable to harness its curious and interesting properties in practical applications. We have taken a step in this direction by using this phenomenon as the waveguiding mechanism in optical fibers. In this talk, we will survey recent advances in the fundamental understanding and application of disordered optical fibers and waveguides.

We demonstrate optical image transport using transverse Anderson localization of light.
The image transport quality obtained in the disordered optical fiber is comparable with or better than the best commercially available multicore imaging fibers with less pixelation and higher contrast. Our results open the way to device-level implementation of the transverse Anderson localization of light with potential applications in biological and medical imaging.

Biography:
Arash Mafi is currently an Associate Professor of Electrical Engineering and Computer Science at the University of Wisconsin-Milwaukee. He received his Ph.D. degree in Physics in 2001 from The Ohio State University. Following postdoctoral appointments at the University of Arizona in Physics and The Optical Sciences Center, he joined Corning Incorporated working on optical fibers and liquid crystal displays. He moved to the University of Wisconsin-Milwaukee in August 2008.

TOMORROW! Seminar: "SWIFTS: a groundbreaking integrated principle for high-performance spectroscopy and optical sensors" by Dr.Christophe Bonneville 6.6.14/11:00am-12:00pm/ CREOL 102

Seminar: "SWIFTS: a groundbreaking integrated principle for high-performance spectroscopy and optical sensors" by Dr.Christophe Bonneville

Christophe BONNEVILLE, PhD

Abstract:
SWIFTS, or Stationary-Wave Integrated Fourier Transform Spectrometer, is a new, highly integrated high-resolution spectroscopy technology that represents a major advance in the field. It is based on a new way of probing an optical standing wave formed by the light to be analyzed without scanning or moving parts. SWIFTS combines groundbreaking nanotechnology research, integrated optics, microelectronics and embedded software, resulting in high-resolution spectrometer technology bundled into a single robust device measuring a few mm². The story of the commercialization of this technology will be part of the presentation. The technology has been implemented into first products providing a high-resolution high-rate solution for the characterization of lasers. It allows for the first time a dynamic view of their behavior. SWIFTS is also the starting point for breakthrough solutions to address Bragg sensing, high-depth Optical Coherent Tomography and Raman Spectroscopy.
