Relentless growth in computational demand is eroding the historical divide between signal transmission and signal processing. Nonlinear optics, where strong, deterministic interactions couple optical signals together, has long promised to bridge this divide by performing computation directly in the optical domain.

In this talk, I will present recent work from our group toward enabling such technologies on two emerging platforms: thin-film lithium niobate (TFLN) and 2D semiconductors.

First, I will present a TFLN vertical-cavity architecture for squeezed-light generation and parallel signal processing. I will then introduce a low-temperature platform based on 2D transition metal dichalcogenides, in which quantum light is generated from a strongly interacting many-body ensemble of excitons.

Together, these results illustrate how material development and engineered photonic environments can turn nonlinear and quantum optical phenomena into practical resources for the next generation of computing and communication hardware.
