Plasmonic nanoparticles enable manipulation and enhancement of light fields at deep subwavelength scales, leading to structures devices for diverse applications in optics. Despite hybrid plasmonic materials display remarkable optical properties due interactions between components nanoproximity, scalable production nanostructures within a single-crystalline matrix achieve an ideal plasmon-crystal interface remains challenging. Here, novel approach is presented realize efficient in-lattice...
High-quality micro-resonators on thin-film lithium niobate (TFLN) have emerged as an ideal platform for on-chip nonlinear optical applications due to their strong light confinement and excellent natural properties. Here, we present high-efficiency second-harmonic generation (SHG) in a TFLN based the modal phase matching quasi-phase matching. By optimizing phase-matching conditions through thermal tuning, demonstrate SHG efficiency of 149,000%/W low power regime. Furthermore, achieve absolute...

The thickness-dependent third-order nonlinear optical properties of two-dimensional β-InSe and its potential applications as a saturable absorber in pulsed laser generation are investigated. InSe sheets with different layers prepared by the chemical vapor deposition. Using open-aperture femtosecond Z-scan technique at 1030 nm, modulation depth absorption coefficient obtained to be 36% -1.6 × 104 cm·GW-1, respectively. intrinsic mechanism layer-dependent energy band structure evolution is...
Two-dimensional (2D) van der Waals heterostructures (vdW HSs) composed of transition metal dichalcogenides (TMDCs) have emerged as frontrunners in the optoelectronics field, owing to their exceptional optical and electrical properties. Recent research on intrinsic interlayer charge transfer mechanism has been primarily focused Type II HSs, while metal-semiconductor (MS) vertical promising for advancing photodetector technology, received comparatively less attention. Here, we reveal first...
Functional two-dimensional (2D) materials have been extensively explored for a wide range of applications such as energy generation, low-power computing, and biosensing. In this work, we present an approach involving the integration six-layer platinum diselenide (PtSe2) interlayer between thin gold film SiO2 substrate to induce spontaneous formation plasmonic nanostructures (nanoribbons) on upper (∼8 nm) under 1030 nm femtosecond laser irradiation. The periodic is attributed deposition that...
