Paper Abstract

Pure, defect-free bulk semiconductor is the foundation of electronics. On its own, however, perfect periodicity does not give rise to useful function. Selective doping and, better yet, heteroepitaxy, are needed for diodes, transistors, resonant tunneling devices, and lasers. Analogously, perfect photonic crystals are a necessary building block, but not an end in themselves, in the implementation of novel, integrable photonic function. Photonic crystal heterostructures, and interfaces between finite photonic crystals and nonperiodic media, are needed to enable in- and out-coupling, guiding, and wavelength selection, to name a few examples. We summarize herein advances in the realization and design of photonic crystal heterostructures and heterointerfaces. In Section 2 we show how bottom-up self-assembly of colloidal crystals can be merged with top-down pattern definition to determine the orientation and placement of finite-sized photonic crystal regions on a planar substrate. In Section 3 we describe the development of a conceptually- and analytically-tractable theory to enable convenient design using combinations of photonic crystals and homogeneous media.
