Abstract
In some implementations, an emitter device (such as a vertical cavity surface emitting laser (VCSEL) device) may include a substrate layer, a set of epitaxial layers deposited on the substrate layer, at least one active region formed in the set of epitaxial layers, and multiple sidewall reflectors. The emitter device may be configured such that electrical pumping provides an optical gain within the at least one active region for lasing at a first wavelength based on the set of epitaxial layers and lasing at a second wavelength based on the multiple sidewall reflectors.
