20 and 40 Gbps data transmission with small VCSEL arrays
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.
