Abstract
An optoelectronic device includes an off-cut III-V semiconductor substrate, a set of epitaxial layers formed on the off-cut III-V semiconductor substrate, and a horizontal cavity surface-emitting laser (HCSEL) having a laser resonant cavity formed in the set of epitaxial layers. The same or another optoelectronic device includes a semiconductor substrate; a laser, epitaxially grown on the semiconductor substrate and having a laser resonant cavity; a semiconductor device, epitaxially grown on the semiconductor substrate and separated from the laser by a single trench having a first vertical wall abutting the laser and a second vertical wall abutting the semiconductor device; and at least one coating on at least one of the first vertical wall or the second vertical wall. The laser resonant cavity of the laser has a horizontal portion parallel to the semiconductor substrate, and each of the first vertical wall and the second vertical wall is oriented perpendicular to the semiconductor substrate.
