Sub-micron periodically-poled lithium niobate waveguide for integrated nonlinear optics

open access: yes, 2016
We present the first integrable periodically-poled lithium niobate (PPLN) waveguide with a submicron waveguide core that is realized on a silicon nitride thin film lithium niobate platform.

Nonreciprocal Electro‐Optic Intermodal Scattering With Momentum Engineered RF Waves

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
We demonstrate highly selective nonreciprocal intermodal scattering in thin‐film lithium niobate using slow‐wave RF transmission lines. This electro‐optic momentum engineering approach enables magnet‐free nonreciprocal devices with a single RF input. ABSTRACT Spatiotemporal modulation approaches have been often employed as alternatives for producing ...

Tunable and stable micro-ring resonator based on thin-film lithium tantalate

open access: yesAPL Photonics
As ferroelectric materials, lithium tantalate and lithium niobate share similar material characteristics, such as a high Pockels effect and nonlinear optical coefficients. When compared to lithium niobate, lithium tantalate offers a higher optical damage

Facile synthesis of Lithium Niobate squares by a combustion route

open access: yes, 2006
A combustion synthesis of lithium niobate (LN) squares from activated niobium oxide (Nb2 O5.nH2O) and Li2CO3 was studied to understand all the chemical reactions involved, and the nucleation and square-growth mechanisms.

Nonlinear Photonics for Sub-Terahertz Sources [PDF]

open access: yesEPJ Web of Conferences
Terahertz technologies offer unique advantages for communication, sensing, and imaging, yet integrated platforms struggle to perform efficiently in this range. Thin-film lithium niobate, a nonlinear photonic platform, enables compact, broadband, and high-

Nanophotonic lithium niobate electro-optic modulators

open access: yesOptics Express, 2018
Modern communication networks require high performance and scalable electro-optic modulators that convert electrical signals to optical signals at high speed. Existing lithium niobate modulators have excellent performance but are bulky and prohibitively expensive to scale up.

Growth and Thermal Properties of Mg-Doped Lithium Isotope Niobate (Mg:7LiNbO3) Crystal

open access: yesCrystals, 2018
An Mg-doped isotope lithium niobate (Mg:7LiNbO3) crystal was successfully grown from 7LiOH, Nb2O5, and MgO using the Crozchralski method. The weight of the as-grown crystal with good quality was about 40 g.
