This study revisited established waveguide fabrication technologies on lithium niobate (LN) and potassium titanyl phosphate (KTP) and provided a comparative analysis of their performance for type-0 quasi-phase matched second-harmonic generation at 1.55 mu m. It identified gaps in waveguide performance below theoretical predictions, discussing possible reasons and providing readers with a roadmap for choosing the most appropriate waveguide type and material choice between LN and KTP for desired performance of targeted applications.
Established waveguide fabrication technologies on lithium niobate (LN) and potassium titanyl phosphate (KTP) were revisited, and a comparative analysis of their performance for type-0 quasi-phase matched second-harmonic generation at 1.55 mu m was provided based on literature data and our simulations. This analysis aided identifying gaps where the waveguide performance is below the theoretical predictions, and the possible reasons are discussed. It provides the reader with a roadmap for choosing the most appropriate waveguide type and material choice between LN and KTP for desired performance of targeted applications. (c) 2021 Author(s).
