CREOL at 25: A Full Spectrum of Achievements

Patricia Daukantas

A quarter-century ago, the Florida legislature funded an optics center to diversify the economy of the state’s central region. Today, it has grown into a full-fledged photonics college known for world-class research. more>>


Freeform Optical Surfaces: Report from OSA’s First Incubator Meeting

Kevin P. Thompson, Pablo Benítez and Jannick P. Rolland

Just as business incubator programs are designed to support the development of fledgling companies, OSA’s new incubator meeting series is structured to encourage the growth of exciting new areas within optics. The first one was devoted to the topic of freeform optics—a field that is actively evolving due to recent technological advances. more>>
