| الوصف: | Tamm plasmons, or optical Tamm states, are electromagnetic modes that exist at the interface between a Distributed Bragg Reflector (DBR) and a metallic layer. They are of high interest for the design of new light sources, thanks to the metallic part, which can provide 3D confinement and control of the optical mode but also electrical injection of the structure, in order to excite light emitters. Many light emitting devices could be realised using this dual function, such as integrated polarised light sources, surface plasmon generators or large-scale addressable laser arrays. This PhD work mainly consisted in pushing Tamm light emitting devices towards applicability, with the development of their room-temperature operation and electrical pumping, as opposed to previous demonstrations which were carried out under cryogenic temperature and optical pumping. Semiconducting heterostructures based on ternary alloys of AlGaAs were used for this development, but our results are highly transposable to other families of materials. The first part of this work focused on obtaining a laser effect at room temperature. By improving the structure with the insertion of a low-index layer between the semiconductor DBR and the metal, the ohmic losses in the metal were reduced, thus enabling lasing operation at room temperature. The second part of this work was about achieving the electrical injection of Tamm-based light sources. Starting from a doped DBR with quantum wells, we developed two processes, mostly based on cleanroom microfabrication techniques, to enable electrical injection. The first one, inspired by common microfabrication techniques, has not proved to be successful, due to the degradation of the DBR surface by some standard fabrication steps, and to the strong sensitivity of the Tamm plasmon to the surface composition of the DBR. Therefore, we developed a second method. Its originality lies in a permanent protection of the part of the DBR on which the metallic element will be deposited to form the Tamm mode and ... |
