ABSTRACT:
A light emitting device includes a light emitting active layer, electrodes to supply carriers to the active layer and a resonator enclosing the active layer with high reflectance for light radiated in the active layer. An electrode may be used to apply an electric field to change the wavelength of light radiated in the active layer. The spontaneous emission probability is controlled or modified to obtain high light emission efficiency or a high degree of light modulation.
