Title: OPTOELECTRONIC DEVICE WITH LIGHT-EMITTING DIODE WITH EXTRACTION ENHANCEMENT
Abstract:
The invention relates to an optoelectronic device (30) comprising an active region (18) designed to supply electromagnetic radiation and sandwiched between first and second semiconductor layers (14, 16), the first semiconductor layer defining a face (20), the optoelectronic device also comprising a diffraction grating (32) designed to extract the electromagnetic radiation from the first semiconductor layer, the diffraction grating comprising holes (36) extending into the first semiconductor layer from said face, the width of the holes, measured in a plane parallel to said face, increasing from a central part of the diffraction grating up to a peripheral part of the diffraction grating.
