Semiconductor nanowires are filamentary crystals with a tailored diameter between few to few hundred nanometer. Their special shape and dimensions render them especially interesting for photonic applications. In my talk I will discuss several photonic applications of nanowires. I will start by showing how to modify light absorption and emission of nanowires by coupling them to plasmonic elements [1]. I will then follow by explaining the use of III-V nanowires for solar cell applications. I will show how, by choosing the adequate diameter and length, it is possible to obtain absorption cross-sections much larger than the nanowire physical size. This concentration effect can be used to increase the efficiency of nanowire-based solar cells and to reduce considerably the use of materials [2].
