OSA Optical Computing Incubator: Day 2

By Shuai Sun | Posted: 11 December 2015


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.

OSA Optical Computing Incubator: Day 1

By Shuai Sun | Posted: 10 December 2015


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.

OSA Levitated Optomechanics Incubator Part 2

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.

Adaptive Structured Illumination Incubator

By Marcia Lesky | Posted: 19 November 2015

  • What are the barriers for super-resolution at depth?
  • What are the fundamental limits in fibre imaging (resolution, correction, speed)?
  • What are the challenges of using structured illumination for in vivo imaging?

These are just a few of the questions that were explored at last week’s Adaptive Structured Illumination Incubator. Hosted by Meng Cui from Purdue University, US, and Kishan Dholakia and Michael Mazilu from the University of St. Andrews, UK, this Incubator used invited talks and moderated group discussion to allow experts to cross-fertilize ideas in applications of structured illumination throughout photonics.

Optical Biosensors Incubator Meeting Day 2

By John Goertz | Posted: 11 November 2015

The second half of the Optical Biosensors Incubator deviated somewhat from the highly technical nature of the prior discussions. While several members did discuss progress in various scientific efforts, focus shifted to the broader topic of bringing biosensing technologies to market, and several discussions challenged all those in attendance to think critically on how the status quo relates to the practical, realistic future of the field.

Optical Biosensors Incubator Meeting

By John Goertz | Posted: 10 November 2015

The OSA Optical Biosensors Incubator brings together the leading minds in the field to critically discuss key topics of central importance to this community: “labeled” as compared to “label-free” sensing, digital or single-molecule analyte detection, point-of-care applications, as well as commercialization of optical biosensors. As the Incubator got underway, opening remarks recalled the historical progress in the field starting with the light microscope to today’s optical gene chips to the potential of the liquid biopsy in the future. David Nolte, of Purdue University, gave the day’s first keynote presentation on biointerferometry. He discussed the various manufacturing techniques and optical techniques amenable to different styles of interferometry such as speckle, fringe analysis, phase-contrast, in-line and micro-diffraction interferometry.

Next Steps for Label-free Optical Techniques in Diagnostics & Imaging

By Marcia Lesky | Posted: 22 September 2015

Last week’s Incubator on Label-free Optical Techniques for Biomedical Diagnostics & Imaging participants identified opportunities and challenges for label-free optical techniques and concluded with a clear call to continue the conversation. The hosts will continue to work with the participants to produce a white paper that will outline a prioritized list of recommendations to address the existing challenges and accelerate the translation of label-free optical techniques for clinical practice.
