Laser Focus World’s Innovators Awards program celebrates the disparate and innovative technologies, products, and systems found in the photonics market.
Based on the impartial ratings by our judges, awards were assigned in four different levels—Bronze, Silver, Gold, and Platinum—to companies or organizations that demonstrated excellence in a product or technology, an application, or in research and development.
Submissions were judged on originality; innovation; their impact on designers, systems integrators, or users; whether they fulfilled a new market need; leveraged a novel technology; and/or increased productivity.
To celebrate our third annual Innovators Awards Program, Laser Focus World held a webcast ceremony on October 12, 2020, for all honorees. Here, in their own words, the 2020 group of honorees provides a look at where we stand on the leading edge of photonics products and applications.

OPTICS | MIRaGE: Multiscale Inverse Rapid Group-theory for Engineered-metamaterials
MIRaGE uses scientific knowledge developed from molecular spectroscopy on how the symmetry of a natural molecule affects its optical behavior and properties to design a metamaterial with comparable properties. By making the comparisons that molecules in chemistry are analogous to metamolecules in electromagnetics and that molecular modes of vibration are analogous to the fundamental resonant electrical current modes in a metamaterial, the principles of symmetry and point groups can be translated to electromagnetics. Serving as a basis for metamaterials design, MIRaGE facilitates the quest for unusual electromagnetic behaviors that can be associated with optical properties.
