Summary

• What is new: A platform-agnostic laser integration technique that works across a variety of platforms with different refractive indices.
• Why this is important: The reliance on off-chip bulk lasers in integrated photonics limits the compactness and efficiency of devices across various applications.
• What the research proposes: A novel, versatile laser integration method using a two-step micro-transfer printing technique, applicable to multiple platforms without modifications.
• Results: Nearly identical laser performance was achieved across different platforms, with successful experimental validation on lithium niobate and silicon nitride platforms. Additionally, the technique enabled the integration of a laser with a resonant electro-optic comb generator, producing over 80 comb lines.
