Mid-infrared frequency comb generation via cascaded quadratic nonlinearities in quasi-phase-matched waveguides

, 2018
We experimentally demonstrate a simple configuration for mid-infrared (MIR) frequency comb generation in quasi-phase-matched lithium niobate waveguides using the cascaded-$\chi^{(2)}$ nonlinearity.

Integrated lithium niobate photonics

Nanophotonics, 2020
Abstract Lithium niobate (LiNbO3) on insulator (LNOI) is a promising material platform for integrated photonics due to single crystal LiNbO3 film’s wide transparent window, high refractive index, and high second-order nonlinearity. Based on LNOI, the fast-developing ridge-waveguide fabrication techniques enabled various structures ...

Ferroelectric‐Polarization‐Driven Structural Engineering of Bi3Nb17O47 Anodes for High‐Performance Lithium‐Ion Batteries

Advanced Science, EarlyView.
A transformative ferroelectric‐polarization strategy is employed to overcome the intrinsic limitations of tungsten bronze (TTB)‐type anode materials in metal‐ion batteries, using Bi3Nb17O47 as a model system. By exploiting the non‐centrosymmetric crystal structure and field‐induced ionic displacements, controlled structural engineering with ...

Nanophotonic lithium niobate electro-optic modulators

Optics 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.
