WebPhotonic Crystals. Photonic Crystals From Wikipedia: “Photonic Crystals are periodic optical nanostructures that are designed to affect the motion of photons in a similar way that periodicity of a semiconductor crystal affects the motion of electrons. Photonic crystals occur in nature and in various forms have been studied scientifically for the last 100 years”. http://ab-initio.mit.edu/photons/tutorial/L1-bloch.ppt
WebThe photonic crystal rod has 0.8 m length and 15 dB cladding absorption at 976 nm. The core diameter and cladding diameter are 85 μm and 260 μm, respectively. For pumping, a high-power fiber-coupled laser diode is used as the drive source and up to 250 W continuous wave (CW) power can be emitted.
