Abstract

See full text

A semiconductor nanolaser includes a rib formed by a stack of layers, in which stack central layers (33, 34, 35) forming an assembly of quantum wells are placed between a lower layer (32) of a first conductivity type and an upper layer (36) of a second conductivity type. Holes (42) are drilled right through the thickness of the rib, wherein the lower layer includes first extensions (38, 40) that extend laterally on either side of the rib, and that are coated with first metallizations (42, 44) that are located a distance away from the rib. The stack includes second extensions (45, 46) that extend longitudinally beyond said rib, and that are coated with second metallizations (47, 48).
