III-V Nanowires for Optoelectronics

Applications

In general, our research relates to applications based on either light emission or light absorption, e.g. optical data transmission or energy harvesting. Since the nanowire geometry facilitates the integration of dissimilar materials, substrates with attractive properties can be employed that were excluded for planar growth. Furthermore, the spectral region of optoelectronic devices can be widened. Also, radial nanowire heterostructures drastically increase the size of the active region, which is associated with stronger light emission and absorption. In addition, light-matter interaction can be tailored by design of nanowire dimensions and their arrangement in arrays.

Currently, we work towards a laser monolithically integrated on Si. Such a laser is of strategic relevance for the application field Si photonics. Our concept will provide the direct coupling of light between arrays of vertical III-V nanowires and planar Si waveguides. This project (MILAS) is funded by the Federal Ministry of Education and Research, and our partner is Technical University of Berlin.
