Generalized model of anisotropic thermo-optic response on thin-film lithium niobate platform
Joonsup Shim, Seonghun Kim, Shengyuan Lu +5
Thermo-optic (TO) control is crucial for thin-film lithium niobate (TFLN) photonic integrated circuits (PICs), offering a simple and practical method for low-frequency and DC tunin…

Rapid adiabatic couplers with arbitrary split ratios for broadband DWDM interleaver application
Daehan Choi, Woo-Joo Kim, Young-Ik Sohn
We experimentally demonstrate a compact and broadband rapid adiabatic couplers (RACs) with arbitrary power split ratios, achieved through the combination of translational offset an…
