Negative Kerr Contribution on Hybrid SiN-CNTs Waveguides
Silicon nitride (SiN) waveguides are valued in integrated photonics for their broad transparency, low losses, and CMOS compatibility, enabling scalable device fabrication [1]. However, their low Kerr nonlinearity limits applications like frequency combs and four-wave mixing. Hybridization with different materials, such as chalco-genide glasses, oxides, semiconductor carbon nanotubes (CNTs), and more, are promising solutions, since they provide high Kerr coefficients and low two-photon absorption. The advantage of the latter material is the chirality-dependent nonlinear optical properties [2].
