_Note :
this PhD offer is fully funded and is certain to begin in the year 2024._

Silicon emitting centers (SECs) are local modifications of the crystalline lattice of bulk silicon, in the form of interstitial or substitutional atoms, that can emit light in or close to the near-infrared telecom wavelength bands.

SECs are a novel and recent approach to integrating telecom optical sources in silicon photonics components and are beginning to gain traction at national and international levels i].[ii] [iii.

While promising results have already been published, there are still many issues to be studied in detail:
how to generate the desired point defects in a spatially deterministic way? How can they be best integrated into silicon photonics components? What performances should we target?

In this thesis, the recruited PhD student will work on:

The development of innovative techniques for the creation of SEC populations by using the equipment available on the Nanolyon platform (nanofabrication equipment) or at the CLYM centre (advanced microscopy platform), or through national collaborations.
The study of the optical properties of the generated SECs (lifetime of the excited state, quantum efficiency under optical pumping, studies as a function of the system temperature, etc.).
Design, fabrication and characterization of photonic structures (photonic crystals,...) that can enhance and control the direction and polarization of photons emitted by SECs coupled to optical modes.
This work will build on existing expertise in the host laboratory and on work already carried out on this theme and with various partners iv],[v],[vi. The ultimate goal of the thesis is to demonstrate the stimulated emission, or even an emission in the Superradiance regime, of a large population of SECs hosted in a photonic crystal.
