Many existing approaches rely on electronic conversion, slow tuning mechanisms, or wavelength-sensitive resonant structures, which limits the scalability of integrated photonic computing systems. In our new Nature Communications paper, “Integrated van der Waals waveguides for all-optical nonlinear photonic circuits,” we demonstrate an integrated MoS₂ waveguide platform for broadband all-optical nonlinear activation.
