Abstract

We demonstrate near-ultraviolet frequency two-dimensional organic-photonic-crystal laser using resonator structures that offer two-dimensional distributed feedback at room temperature. The gain medium is N,N′-di-1-naphthyl-N, N′-diphenylbenzidine (NPB) which is deposited on lithographically patterned silica structure. We observe surface emitting lasing action with the central beam normal to the surface and the far-field emission characteristics of this laser. The devices operate in the blue spectral region, and exhibit very low threshold energies for oscillation (0.3 kW/cm2). The far field is also shown to contain information about the quality of the photonic crystal. This emission pattern offers a convenient and powerful way to evaluate the nature of laser action in such resonators. © 2007 Wiley Periodicals, Inc.
