Point to point VCSEL-based free space optical data link for board-to-board communications

Abstract

D-Lightsys considers free space optical links for intermediate communication distances ranging from a few centimeters to one or two meters. In this paper, we present the initial simulations and the first experimental characterizations of a VCSEL-based point-to-point free space interconnect on distances ranging from 16cm to 40cm targeting bit rates up to 2.5Gbps.
