Second-Order Nonlinear Microresonators on Thin-Film Lithium Tantalate
Andrea Cordaro, Yunxiang Song, Keith Powell +12
Nonlinear frequency conversion enables coherent light generation in spectral regions that conventional lasers cannot reach directly and is foundational to the generation of squeeze…
Hysteresis and trap emission in dc-biased integrated lithium niobate electro-optic modulators
Matthew Yeh, CJ Xin, Donald Witt +3
The electro-optic effect is crucially important for low power and efficient tuning of integrated photonic circuits. However, in electro-optic materials such as lithium niobate, dc…
Ultrafast programmable Bragg reflection in photonic integrated circuits
Yunxiang Song, Pawan Ratra, Danxian Liu +12
Distributed Bragg reflectors (DBRs) are foundational building blocks of classical and quantum photonic technologies. However, their optical responses are typically fixed upon fabri…
Understanding Intrinsic Loss in Thin-Film Lithium Niobate Ring Resonators via Adiabatic Coupling
Xinrui Zhu, Hana K. Warner, Yunxiang Song +2
Thin-film lithium niobate (TFLN) has emerged as a versatile integrated photonics platform, combining strong electro-optic and nonlinear effects. Among TFLN devices, ring resonators…
