Description
This project focuses on the control of radiative emission of Erbium ions in photonic crystal nanostructures made of crystalline Silicon, with the goal of achieving laser emission around 1.54 micron wavelength. To this purpose, photonic crystal waveguides and nanocavities will be fabricated in Si membranes containing Erbium ions. Photonic structures will be designed such that the high-Q cavity modes be resonant with the narrow lines corresponding to Er emission, in order to tailor the radiative dynamics and to enhance optical gain. Micro-photoluminescence and pump-probe experiments under suitable pumping conditions will probe the radiative emission of Er, to achieve net gain and lasing threshold. Theoretical studies of Er emission coupled to nanocavity modes will allow exploring cavity quantum electrodynamics effects. The proposal builds on a new partnership involving a number of Young Researchers by leading groups with complementary expertise in Silicon photonics, nanotechnology, nano-photonics, and quantum optics.
