A computational neural network (a form of artificial intelligence) was able to learn how a multilayered nanoparticle scatters light by learning the relationship between the nanoparticle’s structure and its behavior, based on thousands of training examples. After the relationship was learned, the program could essentially be run backward to design a particle with the desired set of light-scattering properties. This inverse design technique could lead to a way to custom-design nanoparticles for use in displays, cloaking systems, or biomedical devices. It could also provide a means...Read full articleRelated content from Photonics MediaARTICLESData-Based Design Method for Metamaterials Uses Artificial IntelligenceThe process for designing metamaterials could be improved by using data-driven approaches based on deep learning, according to researchers at Pohang University of Science and Technology (POSTECH)....Photonics.com 7/19/2019Working Remotely?

Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics, and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer. Lately demands from industry and research have...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors) and fold light (prisms).
