Integrating 2D crystals and waveguide circuits: Active components and versatile exciton spectroscopy (W02)

• Subject Area: Experimental Condensed Matter Physics ; Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 441234705

In project W02, we will explore previously inaccessible features of the unique excitonic properties of transition-metal dichalcogenides (TMDCs) by establishing tailored near-surface interactions between TMDCs and laser-written freeform optical pathways within a carrier chip. The fundamental insights and technological advances developed in the process will allow us to incorporate TMDC-augmented waveguides and characterize their enhanced optical nonlinearity, as well as the non-Hermitian dynamics mediated by their absorption and optical gain. Our project intends to pave the way towards harnessing two-dimensional materials as functional elements in a new class of advanced photonic circuitry.
