Abstract: Wavelength conversion processes such as spontaneous parametric down conversion (SPDC) and optical parametric amplification (OPA) are key elements in integrated quantum optics. On-chip integration of these functionalities would allow for increased performance and huge scaling opportunities. However, CMOS-compatible platforms such as silicon and silicon nitride (SiN) lack a $\chi^{(2)}$ nonlinearity due to their inversion symmetry. This work provides a solution by heterogeneously integrating periodically poled lithium niobate (PPLN) onto SiN wave-guides through micro-transfer printing $(\mu \text{TP})$[1]. The $\mu \text{TP}$ method is a scalable back-end process, allowing the fabrication of the photonic integrated circuit to remain CMOS-compatible.
