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…

Simulating Quantum Light in Lossy Microring Resonators Driven by Strong Pulses
Youngbin Kim, Seongjin Jeon, Young-Ik Sohn
In this work, we present a quantum theory for pulsed photon pair generation in a single ring resonator. Our approach combines the Heisenberg picture input-output formalism with the…
