| Recent Advances in Volume Bragg Grating Technologies |
Presented by Dr. Alexei Glebov, CEO and President of OptiGrate Corp Time: 10:00 a.m.-11:00 a.m., March 21, 2014 Location: A718, SINANO Abstract: Owing to their fine spectral and angular filtering capability, a new type of optical components - volume Bragg gratings (VBG) - proved to be indispensable for numerous applications in optics and photonics. In the recent decade VBGs in photo-thermo-reflective (PTR) glass have found wide utilization in various applications, such as longitudinal and transverse mode selection in diode, fiber, and solid-state laser resonators, stretchers and compressors for picosecond and femtosecond lasers, mirrors for high brightness dense spectral beam combining, angular beam deflectors/magnifiers, and ultra-narrow line filters for Raman spectroscopy. In this presentation we will review recent progress in VBG technologies and demonstrate achievements in several areas of VBG applications such as ultra-low frequency (THz) Raman spectroscopy, high power narrow band diode lasers, ultra-short pulse lasers, and high power spectral beam combining. Also unique properties of VBGs enable recording of multiple elements in the same volume of recording material (volume multiplexing). In the presentation we will review a variety of novel optical components that can be created using this technology. Biography: Dr. Glebov has started his industrial career at Bell Laboratories in NJ and moved to Silicon Valley in the late 1990s. He worked for over a decade in various engineering and management positions with key optoelectronics manufacturers such as Finisar, Fujitsu, and Lucent Technologies. In 2008, Dr. Glebov was appointed CEO of OptiGrate Corp and moved to Orlando, Fl to lead the company to a greater success. Dr. Glebov’s experience ranges from advanced technology development to commercialization, new product introduction, and manufacturing of leading edge optoelectronic devices and systems. He received his Ph.D. and M.S. in Applied Physics from Georg-August University of Gottingen, Germany, and University of St. Petersburg, Russia, respectively. He has 35 US patents and more than 50 peer-reviewed journal publications and book chapters. He is a frequent invited lecturer, editor of numerousconference proceedings bands, conference and symposium chair, and executive organizing and program committee member at major professional photonics meetings and trade shows. Company: OptiGrate Corp designs and manufactures unique holographic optical elements and filters for optoelectronic, analytical, medical, and securityapplications. Since 1999, OptiGrate has received numerous awards and grants from the US government agencies to develop and manufacture cutting-edge technology products. OptiGrate’s volume Bragg gratings were delivered to more than 400 customers on 6 continents. Today OptiGrate has 35 employees and is located in the Orlando metro area, several miles away from the University of Central Florida where we design, develop, and make all of our products. Our unique facility includes a photosensitive glass production area, a holographic area, and a laser development laboratory. In 2011 OptiGrate was elected one of the 50 Florida Companies to Watch and received the Small Manufacturer of the Year award in 2012 from the Manufacturers Association of Central Florida. |
