Abstract: A heterostructure with reduced optical losses is disclosed. The heterostructure includes a set of n-type layers; an active region that generates radiation at a peak emitted wavelength; and a set of p-type layers located adjacent to the active region. A reflective structure can be located adjacent to the set of p-type layers. A thickness of the set of p-type layers can be configured to promote constructive interference of the reflected radiation with radiation emitted by the active region in a direction toward the set of n-type layers.

Abstract: A solution for fabricating a semiconductor structure and the corresponding semiconductor structure are provided. The semiconductor structure includes a plurality of semiconductor layers grown over a substrate using a set of epitaxial growth periods. During each epitaxial growth period, a first semiconductor layer having one of: a tensile stress or a compressive stress is grown followed by growth of a second semiconductor layer having the other of: the tensile stress or the compressive stress directly on the first semiconductor layer.

Abstract: An optoelectronic device with reduced optical losses is disclosed. The optoelectronic device includes a set of n-type layers; an active region that includes at least one quantum well configured to generate radiation at a peak emitted wavelength and at least one barrier; and a set of p-type layers disposed on the active region. A reflective layer can be disposed on the set of p-type layers. The set of p-type layers can included an electron blocking region, and a thickness of the electron blocking region can be 80% or less than a thicking of the set of p-type layers. Additionally, a thickness of the at least one barrier can be 20% or less than the thickness of the set of p-type layers.

Abstract: A substrate includes structures formed on a growth surface of the substrate. The structures are formed in a multi-periodic pattern, which includes a first plurality of groups of structures. Each group of structures has a characteristic spacing between adjacent structures in the group. Each group of structures is separated from an adjacent group of structures by a second characteristic spacing. The second characteristic spacing is at least 1.5 times larger than the first characteristic spacing.
