Nonlinear quantum optical effects in freeform dielectric waveguides

Dielectric waveguides are key components of photonic integrated circuits (PIC) connecting platforms made of different materials. In this way it is possible to combine the complementary advantages of different integration platforms. The use of PIC allows the transmission of information signals imposed on optical wavelengths. The freeform dielectric waveguides also called photonic wire bonds are fabricated “in situ” by additive nanofabrication techniques once the positions of the input and output are measured and the trajectory is computed. This method can compensate for inaccuracies of the placement of the platforms and so increase the transmission efficiency. In the proposed project we focus on the nonlinear effects which could be present in the waveguides and also describe the transmission of light in quantum regime in order to extend current considerations and understand physical phenomena taking place in these structures. In this way we can develop alternative tools for fast calculation of transmission and optimization of the shape of waveguides.
