Nanophotonic Processor Uses Optics to Speed Deep Learning Computations
Using light instead of electricity to power neural networks could improve the speed and efficiency of certain deep learning computations, especially tasks that involve repeated multiplications of matrices that can be computationally intensive for conventional CPU or GPU chips. While many proposed uses of photonic computers for deep learning have proven impractical, a light-based neural-network system developed by a team at Massachusetts Institute of Technology (MIT) could be useful for deep-learning for some applications.

Novel Photopatterning Approach Builds OLEDs from the Ground Up
A light-mediated methodology for growing patterned, emissive polymer brushes with micron feature resolution could lead to a more efficient, cost-effective method for creating OLED displays. Although many fabrication methods for OLEDs exist, they all have limitations with regard to scalability, pattern control or feature resolution. To photopattern OLEDs more efficiently, emissive polymer brushes were grafted from conductive substrates via photocatalysis.

Multispectral Imaging Reveals Ancient Hebrew Inscription
Multispectral imaging techniques have unearthed an invisible inscription on the back of a pottery shard that has been on display at The Israel Museum for over half a century. The ostracon — ink-inscribed pottery shard — dates back to ca. 600 BCE. The inscription on the front of the shard has been studied by archaeologists and biblical scholars alike, but the back of the pottery was thought to be blank.

Optical Approach Delivers Fast, Scalable Data Transmission
Microresonator soliton frequency combs have been shown to considerably increase the performance of wavelength division multiplexing (WDM) techniques in optical communications. The technology could be used to develop efficient, highly scalable communication systems.

Laser-Induced Graphene Inhibits Biofouling, Kills Bacteria
Laser-induced graphene (LIG) has been shown to be effective in resisting biofouling (the buildup of biological material on wet surfaces) and, when used as electrodes with a small applied voltage, in destroying bacteria. The antibiofilm activity of LIG surfaces and electrodes could lead to efficient protection of surfaces that are susceptible to biofouling in environmental applications.

Optics-Based Tools for Cancer Care
Tue, Jun 27, 2017 2:00 PM - 3:00 PM EDT
Nirmala (Nimmi) Ramanujam, Ph.D., will speak on optical tools and techniques she is developing for cancer screening in resource-limited settings. Professor Ramanujam is leading a multi-disciplinary effort to translate these technologies to clinical applications in the breast and cervix. In addition to her academic efforts, professor Ramanujam has spun out a company, Zenalux, to commercialize several of the technologies developed in her lab and is developing and creating the processes to move technologies further down the commercialization pipeline within Duke. Ramanujam is Robert W. Carr Jr. professor of Biomedical Engineering, professor in Pharmacology & Cancer Biology and Global Health, and founding director of the Global Women’s Health Technologies at Duke University.
