Optical interconnections made using two-dimensional arrays of top-surface-emitting microlasers and integrated free-space optics are discussed for use in chip-to-chip communications. A demonstration setup with a 2 x 2 array of lasers is presented. System parameters, such as light efficiency, the number of data channels, thermal effects, power requirements, and the issue of hybrid integration of laser chips with passive optics, are considered.
