Chaotic systems have a particular quantum behavior and several conjectures remain to be demonstrated concerning their spectrum and their wave functions [1]. Graphs can be chaotic or not and allow a relatively simple theoretical study of the classical and quantum limits [2]. These experiments are easier to carry out in photonics and the formalism fits well to the wave-particle duality of light. We have therefore produced graphs (chaotic or not) where light circulates in silicon waveguides (Fig. 1a) and we study their spectrum (Fig. 1c) and their wave functions (Fig. 1b). The first objective is to verify the validity of the conjectures according to different types of graphs. In a second step, we will inject non-classical light (squeezed light or entangled photons for instance) to know if entanglement is sensitive to chaos. The silicon graphs are fabricated in the C2N cleanroom. Their design requires numerical simulations performed under the supervision of Xavier Chécoury (C2N). The experiments are carried out on a dedicated characterization setup at C2N and the theory is developed in collaboration with Barbara Dietz (Dresden). The student may be involved in one or several of these tasks, depending on his/her preferences.
