Abstract

A surface emission random laser and a manufacturing method thereof, wherein the random laser comprises: a semiconductor die (1) comprising a plurality of semiconductor layers; two or more electrodes (2), attached to the semiconductor die (1) for current injection; an optically active layer (3) placed between two semiconductor layers to produce optical amplification as a response to the current injection; two planar confinement layers (4), arranged over and under the optically active layer (3) configured for light confinement; and one or more scattering elements (5), being holes or grooves drilled in the semiconductor die (1) and extending at least to reach the optically active layer (3) and defining scattering rough surfaces (7) divided into: a proximal scattering surface (8) for optical feedback; and a distal scattering surface (9) for light extraction (6).
