 SNP-2S6 is a two-dimensional, 2D, semiconductor with nonlinear optical, NLO, properties that can be used to create multifunctional electronic photonic integrated circuits, EPIX. This material has been combined with a silicon nitride, SIN, photonic platform to enable on-chip optical modulation and telecom band photo detection. The hybrid device combines efficient SHG processes with up conversion of wavelength from 1560 nm to 780 nanometers. These capabilities offer new possibilities for the development of EPIX.
