1. A hearing aid system comprising:
a multi-laser emitter, wherein the multi-laser emitter includes at least a first laser source positioned on a substrate and a second laser source positioned on the substrate with a configured separation distance between the first and second laser sources, and wherein the multi-laser emitter further includes a diffuser having a configured diffusion angle and positioned away from the first and second laser sources; and
a receiver, wherein the receiver comprises at least one photodetector and a microactuator, the at least one photodetector configured to receive a combined multi-laser output signal based on diffusion by the diffuser of a first laser beam from the first laser source and a second laser beam from the second laser source, wherein the combined multi-laser output signal has a total diffusion angle that is greater than the configured diffusion angle of the diffuser and is based at least in part on the configured separation distance between the first and second laser sources.
