Abstract

We will discuss recent advances involving parallel manipulation of electromagnetic waves on chip-scale photonics using nonlinear photonic devices, computational optimization, and photonic-electronic systems. This enables applications including, but not limited to, data communications at terabits per second. Nonlinear photonics, which transduces a narrow-linewidth laser from one frequency mode into hundreds of frequency modes, will be discussed alongside our experimental insights into second- and third-order nonlinear photonic processes, classical and non-classical parametric oscillations, and optical gain elements. Additionally, we will cover computational optimization for designing photonic devices with desired functionalities and independently controlling optical waves in spatial, spectral, and temporal domains to unlock new functionalities in integrated photonics.
