Photonic Semiconductor Nanostructure Assemblies

Short abstract:

Efficiency, integration and functionality, and small foot-print are some of the key requirements on future generation semiconductor photonic components. Photonic semiconductor nanostructures have the potential to meet these demands by employing their unique geometrical and physical properties for light manipulation, confinement and tailoring light-matter interaction.

This talk gives an overview of our research on semiconductor photonic nanostructures such as nanodisk Mie resonators and nanopillar/nanowires (NWs), both individual and ensembles, focusing on their optical properties and top-down fabrication technologies. Specific applications addressed include broad-band omni-directional anti-reflection, integration of III-Vs on Si for photodetectors and solar cells, biosensors, surface enhanced optical non-linearity and (structural) color filters. We discuss different routes for top-down nanostructure fabrication including combinations of self-assembly for masking, dry etching, solution synthesis, generation and transfer printing of substrate-free nanostructures, novel ion-beam induced self-organization, fabrication of flexible matrices with embedded nanostructures and hierarchical micro/nano structures.
