High-Q photonic crystal Fabry–Pérot micro-resonator in thin-film lithium niobate

Seokjoo Go, Guhwan Kim, Hong‐Seok Kim, Kiwon Moon et autres

Thin-film lithium niobate (TFLN) has emerged as a powerful platform for integrated nonlinear and quantum photonics, owing to its strong optical nonlinearities, wide transparency window, and electro- and piezo-optic properties. However, conventional traveling-wave resonators—such as micro-rings, disks, and racetracks—suffer from curvature-dependent group …

Photonic molecules via coupled thin-film lithium niobate Fabry–Pérot photonic crystal micro-resonators

Seokjoo Go, Guhwan Kim, Hong‐Seok Kim, Kiwon Moon et autres

We demonstrate a photonic molecule platform based on photonic crystal (PhC) Fabry-Pérot micro-resonators on thin-film lithium niobate, featuring standing-wave resonances confined between PhC mirrors. By adjusting the number of PhC unit cells in the coupling region, we achieve tunable mode splitting, validated …
