The Hierarchical Morphology of Dielectric Mirrors

ORAL

Abstract

Active hierarchically structured volume reflection gratings can be fabricated by combining top-down and bottom-up nanomanufacturing techniques. In a typical process holographic photopolymerization (HP) formed lamellar structures of $\sim $200 nm in thickness confining a block copolymer (BCP) to $\sim $100 nm domains. The BCP self assembles into a variety of ordered structures with a period of $\sim $20 nm. A lamellar-in-lamellar structure was achieved and by varying the BCP structure more complex cylinder-in-lamellar and sphere-in-lamellar structures are envisioned. The HP and BCP phase separation/crystallization dichotomy during the formation of hierarchical dielectric mirrors will be discussed.
