Abstract:
1. A semiconductor optoelectronic device, comprising: a) a vertical waveguide, comprising: b) a light-generating element configured to generate optical gain when an injection current is injected to a light-generating layer when a forward bias is applied, wherein the light generating layer is located within the first cavity; and c) a substrate, where a relative positioning of the vertical waveguide and the substrate is selected from two alternatives: d) an injector that injects the injection current to the light generating element, wherein light generated in the light generating element propagates in the first cavity and partially leaks to the second cavity through the second reflector; wherein the light leaked to the second cavity propagates in the second cavity, is reflected by the third reflector, propagates in the second cavity, and returns back to the first cavity through the second reflector; wherein interference between the light propagating in the first cavity and the light returning from the second cavity occurs; wherein phase matching conditions determine one selected vertical optical mode or a few selected vertical optical modes; wherein phase matching conditions determine one selected wavelength or a few selected wavelengths of the emitted light; wherein the vertical waveguide is a broad waveguide having a thickness exceeding three times a wavelength of light in a vacuum; wherein a major part of the optical power is emitted in the one or a few selected vertical optical modes; and wherein the major part is above about eighty per cent; e) a longitudinal resonator that confines the vertical waveguide in a longitudinal direction, the longitudinal resonator comprising: f) at least one stripe that extends in the longitudinal direction; and g) an additional element selected from a group consisting of:
