"combining vertical nanowire with microring laser made from semiconductor nanostructures... single system integrated on a chip, consuming minimal power, ability to shift beam into free space and control the beam shape, and has a tuneable wavefront,... combined an InP microring laser cavity with a vertical InP nanowire antennae that sits in its center and directs photon into freespace with specific beam shapes... less than 5 microns in size and could eventually form a single hologram pixel"
