ABSTRACT:
A planar-type pleochroic light emitting diode and a method of fabricating the same are disclosed, the diode allowing from a single chip a plurality of light emissions having different center wavelengths. Impurity diffusion is carried out by use of a film having a masking effect to an impurity and a different film partially non-uniform in thickness having no masking effect to the impurity to form a plurality of diffusion regions having different depths. The diode has excellent coupling with an optical fiber, can be easily fabricated and is suitable for use in optical multiplex communication.
