DESCRIPTION:Gordon A. Keeler\nDefense Advanced Research Projects Agency (D
 ARPA)\, Microsystems Technology Office\n675 N. Randolph St.\, Arlington\, 
 VA 22203\, USA\, gordon.keeler@DARPA.mil\nDr. Gordon Keeler joined DARPA i
 n August 2017 as a Program Manager in the Microsystems Technology Office (
 MTO). His objective is to accelerate the development of emerging photonic
 s\, electronics\, and integration technologies to open new pathways toward
  revolutionary optical microsystems.\n\nPrior to joining DARPA\, Dr. Keele
 r was a Principal Member of Technical Staff at Sandia National Laboratorie
 s. At Sandia\, his research focused on the creation of advanced optoelect
 ronics and heterogeneous integration techniques to prototype solutions for
  optical sensing\, imaging\, communications\, and high-performance computi
 ng applications. His technical interests include semiconductor lasers\, mo
 dulators\, and detectors\; nanophotonics and plasmonics\; semiconductor m
 aterials and device physics\; radio frequency (RF) and ultrafast optics\; 
 novel photonic materials and their integration with mature platforms\; an
 d microscale optoelectronic packaging technologies.\n\nDr. Keeler has co-a
 uthored more than 100 peer-reviewed publications and conference proceeding
 s\, and holds several patents in the field of photonics. He was the chair
  of the Albuquerque Chapter of the IEEE Photonics Society\, and is an IEEE
  senior member and a member of The Optical Society (OSA).\n\nDr. Keeler re
 ceived the Honors Bachelor of Science degree in Physics from Lakehead Univ
 ersity\, and the Master of Science and Doctor of Philosophy degrees in Ap
 plied Physics from Stanford University. His graduate research focused on c
 ompound semiconductor optoelectronics\, heterogeneous integration of phot
 onics with microelectronics\, and the application of ultrafast techniques 
 to high-performance computing.  \nAfter many years of directed investment
 \, integrated photonics technologies have begun to enable sophisticated so
 lutions for fiber-optic communications. The increasing maturity and availa
 bility of photonic integrated circuits will ultimately enable a variety of
  revolutionary chip-scale applications including LIDAR\, chemical and biol
 ogical sensing\, precision metrology\, quantum information processing\, an
 d free-space laser communications. However\, providing impact in applicati
 ons beyond datacom has proved challenging because the toolset developed fo
 r digital communications often fails to meet the broader needs of new appl
 ications. This talk describes DARPA efforts to improve passive and active 
 integrated photonics components\, along with relevant programs that are dr
 iving technology innovation.\nThe Modular Optical Aperture Building Blocks
  (MOABB) program is an effort to develop optical LIDAR using planar photon
 ics components in the place of bulky optics and slow\, costly mechanical b
 eam steering elements. MOABB creates an optical phased array which combine
 s coherent light from individual emitter elements placed on a wavelength-s
 cale pitch. Electrically-addressed phase modulators control directionality
  for transmit and receive functions. Key MOABB device challenges include t
 he dense integration of small phase modulators\, high-power tunable lasers
 \, and high-speed drive electronics.\nThe Direct On-chip Digital Optical S
 ynthesizer (DODOS) program seeks to develop a chip-scale optical frequency
  synthesizer using a self-referenced optical frequency comb to precisely c
 ontrol the output of a narrowband tunable laser. DODOS has driven the deve
 lopment of high Q microresonators\, chip-scale modelocked lasers\, efficie
 nt frequency doublers\, and wideband passive elements that operate with lo
 w loss across an octave of spectrum.\n
