High‐Speed Integrated Graphene‐Silicon Slot‐Waveguide Electro‐Absorption Modulator at 2 and 1.5 µm Wavebands

Laser &Photonics Reviews, EarlyView.
A high‐speed, efficient, robust, and compact 2‐μm$\mathrm{\mu}\mathrm{m}$ waveband E/O absorption modulator based on a graphene‐silicon slot waveguide is demonstrated. This work represents a significant advancement towards the realization of high‐speed integrated E/O modulators for optical communication systems operating at the 2‐μm$\mathrm{\mu}\mathrm{

Probing water properties of perfluorinated sulfonic-acid membranes with humidity-controlled terahertz time-domain spectroscopy

Perfluorinated sulfonic acid membranes are renowned for their unique proton conduction and chemical/mechanical stability. As water plays a crucial role in their proton conduction that changes with environmental humidity, here we evaluate the robustness ...

Terahertz Spectroscopy on Pyrite

Pyrite is identifiable. The Iron (II) disulfide [FeS2] structure becomes isoclinic with minimal tetragonal [CuFeS2], orthorhombic [FeS2], or monoclinic [AsFeS2] forms. Physical examination validates crystal structure and composition. A tetragonal, pale brassy yellow, 6.0 Moh’s hardness, indistinct cleavage, 4.68 g/cm3 specific gravity, metallic luster,

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

Laser &Photonics Reviews, EarlyView.
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

Laser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...
