Article comprising an organic laser

摘要

An organic laser according to the invention comprises an electrically pumped source of incoherent radiation (16) with organic active region (14), and further comprises a waveguide structure that receives the incoherent radiation. The core (18) of the waveguide comprises organic material that absorbs the incoherent radiation and emits coherent radiation (19) of longer wavelength. The laser forms a unitary structure, with the source of incoherent radiation being close to the waveguide core, exemplarily less than 10 lambda from the core, where lambda is the laser wavelength. Exemplarily the laser is embodied in a planar waveguide laser, in a microdisk laser, or in a laser comprising a photonic bandgap structure. <IMAGE>
