Abstract (en)
[origin: WO2008041138A2] A light emitting device emits light from the surface in a broad spectral range and a broad range of angles tilted with respect to the direction normal to the exit surface. An apparatus for generating wavelength-stabilized light is formed of a light-emitting device, an external cavity and at least one external mirror. Light emitted by the light-emitting device at a certain preselected angle, propagates through the external cavity, impinges on the external mirror and is reflected back. Reflected light undergoes interference with the emitted light. The interference can be constructive or destructive. Constructive interference results in a positive feedback. The positive feedback conditions are met at one or a few selected wavelengths within the luminescence spectrum of the active region. Then the apparatus generates wavelength- stabilized light. An apparatus may operate as a wavelength- stabilized light-emitting diode, a wavelength- stabilized superluminescent light-emitting diode, or a wavelength-stabilized laser, or an apparatus for frequency conversion.
