Voltage-tuned resonant reflectance optical filter for visible wavelengths fabricated by nanoreplica molding

This work describes the first implementation of a plastic-based photonic crystal filter at visible wavelengths that incorporates a variable refractive-index material for voltage-controlled actuation of the transmission wavelength band. Using a replica-molding approach, device structures are inexpensively fabricated over large surface areas, and the fabrication approach enables control of individual regions on the surface of the PC. The talk will describe the device operating principle, rigorous coupled wave analysis and finite difference time domain analysis computer simulation/design methodology, the device fabrication methods, and testing of the reflection/transmission efficiency, tuning range, and response speed.
