Non-Adiabatic Control in Nonlinear Integrated Photonics – NAC-NIP

The object of NAC-NIP is to revisit waveguides array in the perspectives of the recent developments in integrated photonics. In particular, the project will focus on systems composed of only a few waveguides that support only a small number of discrete super modes. This contrast with the seminal arrays of waveguides that were meant to form an effective homogenous medium with continuous bands: diffusion is here limited, but inter-modal transitions are still possible. This will be the occasion to construct a non-adiabatic transfer theory in order to control efficiently this kind of system. The outcome of NAC-NIP will be a better comprehension of symmetry (topology) effects in photonics and in particular how these effects can interplay with nonlinearity. This will serve the demonstration of a low power integrated mode-locked laser; and the realization of advanced filtering functions for the on-chip processing of telecom signal.
