Photonic crystal integrated optical devices

We discuss how photonic crystals control light properties such as the generation, propagation, modulation and conversion of light on the nanoscale. The underlying physical principles and mechanism will be addressed. Discussions will focus on the construction of various nanoscale integrated optical elements and devices. We employ several typical examples to briefly describe different aspects of these devices: how they work, how to fabricate them, and how to characterize their optical properties.
