On-chip integration of 2D layered graphene oxide films for high performing nonlinear optics

All-optical integrated photonic devices based on the nonlinearity offer a powerful solution to achieve on-chip far superior signal processing speeds without the need to convert the optical signal to the electrical domain (or vice versa) as well as the added benefits of a compact footprint, small power consumption, high stability, mass-producibility, and the strong potential to reduce cost. The growing demand for high-performance nonlinear integrated photonic devices has prompted the hybrid integration of two-dimensional (2D) materials with ultrahigh nonlinearity to overcome the limitations of existing integrated photonic platforms. My work focuses on improving the nonlinear performance of these hybrid devices.
