Optical Computing Incubator
Day 1 continued…

 
The afternoon session on day 1 addressed optical computing algorithms and was presided over by Dr. Mark Neifeld, from the University of Arizona.  The focus of the session was on the identification of computational primitives and how their optical implementation is realized.  The central challenges in this area are:
 

  1. The identification of computationally meaningful primitives and their optical realization;
  2. The impact of error propagation in multistage architectures designed to solve challenging problems in computing and signal processing.

Optical Computing Incubator

Welcome to Day 1 of the OSA Optical Computing Incubator, held at OSA Headquarters in Washington, D.C. 9-11 Dec 2015. The topic of this meeting, optical computing, is a merging computing technology uses photons generated by lasers or other light source for higher bandwidth and energy efficiency computation. For the past 60 years, Optical Computing has been a very attractive issue inspired by many related new technologies and nanophotonic devices. The goal for this Incubator is to bring together experts from nanophotonics, physics, computer architecture, computer science and mathematics to explore the current status and the problems that Optical Computing is currently facing, and the prospects of the future for this topic.

Levitated Optomechanics Incubator Part 2

Day one continued…

To round out the earlier post, the final session from day 1 focussed on novel levitated systems. One of the hot developments in optomechanics is the coupling of atomic spin to mechanical motion, and Levi Neukirch from the University of Rochester, USA, introduced us to progress in controlling levitated nanodiamonds. Another way of coupling optomechanics to quantum systems is by using quantum dots, and we were introduced to a novel levitating quantum dot experiment by Yosuke Minowa, from Osaka University in Japan. Both of these systems are limited by absorbing the light which is used to levitate, and Bruce Kane from the University of Maryland USA proposed a solution, in his experiment levitating flakes of graphene in an electric trap.

We were all inspired by these new developments, and it’s very exciting to see levitated optomechanics moving away from optically levitated silica spheres.

Manipulating Objects with Light
 
Welcome to day one of the OSA Levitated Optomechanics Incubator. Optomechanics is the study of the interaction of light with the mechanical motion of objects. Amazingly, mechanical resonators tens of microns in size have been cooled to their motional quantum ground state using light, and have even been placed in quantum superpositions of vibrational motion. By levitating mechanical oscillators, we can push optomechanics beyond the state-of-the-art.
