Random Quasi-Phase-Matched Second Harmonic Generation in Periodically Poled Lithium Tantalate
, 2009 We experimentally observed and explained bulk second harmonic generation via random quasi-phase-matching, derived from a periodically poled lithium tantalate sample with a randomly patterned mark-to-space ...

Research on QPM and Its Cascaded Structure Applied in FOPA
Cybernetics and Information Technologies, 2016 In the research of optical communication, Optical Parametric Amplification (OPA) has been an important point. As a Four Wave Mixing (FWM) effect based nonlinear process, OPA also requires Phase Matching (PM).

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites
Advanced Functional Materials, EarlyView.Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

A Tunable CW Orange Laser Based on a Cascaded MgO:PPLN Single-Pass Sum-Frequency Generation Module
Applied Sciences, 2018 We report an all-solid-state continuous wave (CW) tunable orange laser based on cascaded single-pass sum-frequency generation with fundamental wavelengths at 1545.7 and 975.2 nm using two quasi-phase-matched (QPM) MgO-doped periodically poled lithium ...

Advanced Functional Materials, EarlyView.Top‐down ultrasonication produces highly emissive Cs2ZrCl6:Te4+ nanocrystals (NCs) with a PLQY of 65%, which is higher compared to that of the NCs synthesized by typical bottom‐up hot‐injection synthesis. The colloidal Cs2ZrCl6:Te4+ NCs have been found to be potential candidates for x‐ray scintillation imaging.

Modeling of Random Quasi-Phase-Matching in Birefringent Disordered Media
, 2020 We provide a vectorial model to simulate second-harmonic generation (SHG) in birefringent, transparent media with an arbitrary configuration of non-linear ($\chi^{(2)}$) crystalline grains.

Advanced Functional Materials, EarlyView.Balancing the spatially separated p‐ and n‐type transport pathways in heterojunction‐bilayer OTFTs enables symmetric inverter switching (VM ≈ 0.5VDD), whereas discrete integration of unipolar OTFTs gives polarity‐dependent and resistive responses. ABSTRACT High inverter performance in ambipolar organic electronics requires balanced channel strengths ...

Advanced Functional Materials, EarlyView.Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,
