Abstract

A device for emitting radiation at a predetermined wavelength is disclosed. The device has a cavity comprising a first bulk region and a second bulk region of opposite conductivity type wherein a barrier is provided for spatially separating the charge carriers of the first and the second region substantially at the antinode of the standing wave pattern of said cavity. The recombination of the charge carriers at the barrier create radiation, the emission wavelength of the radiation being determined by the cavity.
