Broad-wavelength-range chemically tunable block-copolymer photonic gels

Youngjong Kang , Joseph J. Walish , Taras Gorishnyy & Edwin L. Thomas

Responsive photonic crystals have been developed for chemical sensing using the variation of optical properties due to interaction with their environment. Photonic crystals with tunability in the visible or near-infrared region are of interest for controlling and processing light for active components of display, sensory or telecommunication devices.
