A vertical-cavity surface-emitting laser (VCSEL) and method of fabrication thereof is provided. The VCSEL includes a mesa structure disposed on a substrate. The mesa structure has a first reflector stack, a second reflector stack, and an active region disposed between the first and second reflector stacks. The active region is configured to cause the VCSEL to emit light having a characteristic wavelength of 910 nanometers. The active region includes alternating layers of quantum wells and barriers, the quantum wells having high indium content (up to 18%). The VCSEL features a first contact layer disposed at least partially on a surface of the mesa structure and configured to serve as an electrical signal layer and a second contact layer disposed at least partially about the mesa structure and configured to serve as an electrical ground.
