An Inverse-Designed Nanophotonic Interface for Excitons in Atomically Thin Materials

Self-Aligned Hybrid Nanocavities Using Atomically Thin Materials

“…The integration of 2D materials with nanophotonic architectures − offers a promising avenue to manipulate light–matter coupling, thereby facilitating the realization of hybrid devices such as lasers, − quantum emitters, , and photodetectors. ,, To achieve optimal device performance, it is imperative to couple 2D materials with cavities exhibiting a high quality factor over the mode volume ratio ( Q / V mode ). The planar air hole photonic crystal (PhC) nanocavities − promise strong light confining in an ultrasmall mode volume, rendering them highly attractive for the aforementioned hybrid device applications.…”

Tunable Optical Nonlinearities in Layered Materials

“…Parametric nonlinear optical processes in layered semiconductors have been extensively explored, both for fundamental studies and for applications, in the past decade. − ,− Nonlinear interactions at the 2D limit do not introduce any dispersion-induced phase mismatch, enabling single-pass nonlinear interactions on the atomic scale without phase-matching constraints. As a result, nonlinear optical processes in atomically thin TMDs can be achieved over ultrabroad operational bandwidths .…”

“…As a result, nonlinear optical processes in atomically thin TMDs can be achieved over ultrabroad operational bandwidths .
