The aim of this line is to fabricate new structures and explore new materials for the study of polariton quantum flow dynamics and their use for optical devices, switches, transistors and logical gates. Inorganic semiconductors are characterized by high quality factors and nonlinearities, while organic materials support tightly bound excitons and can achieve highly processability and nonlinear effects, making them promising for future realization of all-optical or electro-optical devices. When coupled to distributed bragg reflectors mirrors, they can exhibit regimes of ultrastrong coupling and long-range propagation. The aim of this line is the development of all-optical and electro-optical  devices  working at room temperature based on polariton physics. These include polariton laser, polariton logic circuits, self-interfering packet, polariton bloch-surface wave, CNOT gate, fast switches, active waveguide. Oxide-based DBR are built in-home, as well as the evaporation of the active material and the optical measurements. In particular for evanescent modes we have developed a dedicated set-up with leakage microscope, energy resolution and ultrafast time-resolution. The understanding of the fundamental classic and quantum regimes of strong coupling of light and matter, extend the possibility to implement such phenomena in future devices for all-optical logic as the polariton transistor.


On the application side, we report as one of the topmost intriguing applications realizable with polaritonics packets, the realization of an all-optical polariton transistor.

We report the first Polariton Bloch Surface Wave based on the total reflection surface, which offers a fundamental mirror with ultimate 100% reflection hence being able to achieve the strong-coupling regime and leaving the surface free for patterning and operation.

We also achieved the realization and characterization of the ultrastrong coupling regime in metal-organic microcavity.
