Abstract
A photonic device for providing light radiation comprises a wave guide, an N-type semiconductor layer covering the wave guide and an active region formed by a stack of layers made of III-V materials. The photonic device also comprises a plurality of P-type semiconductor pillars arranged on and in contact with the active region. At least a first metal pad is in ohmic contact with the free portion of the N-type layer and at least a second metal pad is in ohmic contact with the P-type pillars.
