State-of-the-art periodically-poled lithium niobate waveguides struggle with extreme fabrication sensitivity, resulting in unpredictable phase-matching wavelengths. We developed a micro-transfer-printed periodically-poled lithium niobate waveguide that enables deterministic phase-matching at a predefined wavelength through optical feedback.
