## Description

- description: "The most prominent form of nonlinear optical (NLO) frequency conversion
    is second harmonic generation (SHG), where incident light interacts with a nonlinear
    medium producing photons at double the input frequency, which has vast applications
    in material and biomedical science. Emerging two-dimensional nonlinear optical
    materials led by transition metal dichalcogenides (TMDs) have fascinating optical
    and\r\nmechanical properties and are highly anticipated to overcome the technical
    limitations imposed by traditional bulky NLO materials. However, the atomic scale
    interaction length and low conversion efficiency in TMD materials prevent their
    further implementation in NLO applications. While some uniaxial strain-engineering
    studies intensively investigated the anisotropic SHG response in TMDs, they did
    not realize giant SHG enhancement by exploiting the opto-mechanical characteristics.
    Herein, we employ proton (Hþ) irradiation to successfully fabricate large pressurized
    monolayer TMD domes (d\x0210 lm) and conduct a comprehensive investigation and
    characterization of their SHG performance enhancement. We show that the intensity
    of SHG is effectively enhanced by around two orders of magnitude at room temperature.
    Such giant enhancement arises from the distinct separation distance induced by
    capped pressurized gas and the hemi-spherical morphology, enabling constructive
    optical interference. Moreover, the unique divergent strain field in TMD domes
    promotes the first experimental study on the anisotropic nonlinear optical behavior
    based on biaxial strain conditions in terms of varying strain orientation and
    relative weights. Our work demonstrates a promising system with enhanced NLO performance
    and well-preserved biocompatibility, paving a way toward the future nano-scaled
    quantum optics design and biomedical applications."
