Title: 3D spherical layer photonic band-gap structures in dichromate gelatin
Authors: Hung, Jenny
Issue Date: 2008
Abstract: Three-dimensional spherical layer photonic band-gap structures were fabricated in dichromate gelatin (DCG) holographic emulsions by a holographic lithography technique. Five spherical layer structures with different radius of curvature were fabricated. The optical transmission spectra of these structures were measured and found to be in agreement with theoretical predictions. Angular dependence optical spectra showed flat reflectance and transmittance independent of the incident angle, demonstrating a complete bandgap independent of the dielectric constant for the first time. SEM images and reflection properties resembling the curved mirror confirms the curved layers of the band-gap structures.
