Low-loss compact lithium niobate photonic integrated circuits

Paper in proceeding, 2023

Lithium niobate (LN) is a promising material among integrated photonics, with applications like high-speed EO modulators, frequency combs, frequency converters, and photon-pair sources [1]. Increasing the system complexity of LN integrated circuits requires large-scale arrays of photonic components [2]. Therefore, an ideal integrated LN waveguide platform should allow dense integration, low propagation losses, and exhibit low fabrication complexity.
