## Abstract Photonic crystals (PhCs) have attracted much attention during the last decade as a solution to overcome the low extraction efficiency of asโgrown lightโemitting diodes (LEDs). In this review we describe the underlying physics and summarize recent results obtained with PhC LEDs. Here, th
