Light is forbidden to travel in periodic nanostructures, such as photonic crystals, when the frequency is within the crystal’s band gap. Using optical wavefront shaping technique, we show the first experimental observations of light transport deep into crystals within the forbidden band and near the band edges of photonic band gap crystals made from silicon.
