ORGANIC PHOTONIC BANDGAP LASERS
Two dimensional photonic bandgaps are formed in thin suspended sheets of glass with an array of submicron holes. An emitting layer of organic material applied to this structure results in beautiful laser phenomena. These lasers emit at wavelengths throughout the visible spectrum. They can be coupled efficiently into photonic bandgap waveguides. Defects in the photonic bandgap structure form laser resonators with sub-micron dimensions. These ultra small lasers have very low thresholds, allow control of spontaneous emission rate and may result in organic laser diodes.
