Available student project - Directional metasurface lasers based on coupled nanowire pairs

Research fields

Project details

Nanolasers with directional emission is of significant research interest, offering potential as compact, coherent on-chip light sources for applications spanning from LiDAR to beam-steering devices. In this project, we demonstrate spatial control of the far-field emission of III-V semiconductor nanowire lasers by engineering the waveguide mode in pairs of optically-coupled nanowires. Importantly, arranging such coupled nanowire pairs into an array can potentially enhance the far-field directionality through non-local resonance effects, highlighting the feasibility of metasurface lasers with highly directional beam emission.
