"optical driver creates programmable patterns light via interference... pump light travels through optical fiber onto which nanolasers are printed... multiple nanolaser arrays driven using light traveling through single fiber... printed nanolaser arrays could be fully controlled by the pump beam interference patterns... also be applied to chip-based silicon photonics systems, which could play a key role in the development of chip-to-chip or on-chip optical interconnects"
