Abstract
We investigate triple and septuple electrically parallel, optically uncoupled 980 nm vertical-cavity surface-emitting laser (VCSEL) arrays with varying intra-array VCSEL-to-VCSEL spacings and oxide aperture diameters. We demonstrate 20 to 40 gigabit-per-second back-to-back data transmission with a bit error ratio of 1x10-13. Our VCSELs enable optical wireless communication for a plethora of sensors, smartphones, and other Internet of Things gadgets.
