Advanced Optical Materials, EarlyView.This work dissects the ultrafast response of polydisperse plasmonic nanorods using two‐dimensional electronic spectroscopy, uniquely combining temporal and spectral resolution. Our ultrabroadband pulses cover both transverse and longitudinal nanorods’ resonances, revealing sub‐200‐fs dynamics and distinct broadening mechanisms.

Red‐to‐Blue Upconversion Nanoparticles Catalyze Aqueous Radical Polymerization
Advanced Optical Materials, EarlyView.Encapsulation of a red‐to‐blue upconversion pair into polymer nanoparticles gives water‐stable heterogeneous nanocatalysts with distinguished stability. Red light irradiation of these nanocatalysts initiates aqueous polymerization of a series of acrylates with high conversion yields.

Infrared Colloidal Quantum Dot Edge Emitting Lasers Integrated on Silicon
Advanced Optical Materials, EarlyView.In this work, the first monolithic integration of Pb‐chalcogenide CQDs in an edge‐emitting DFB laser cavity onto a Si/SiO2 substrate has been demonstrated. The optimizations of SiO2 layer thickness, engineering of the grating duty cycle, and implementing λ/4 phase shift resulted in the achievement of spectrally pure, single‐mode lasing at 1650 nm with ...

Functional-Link Neural Network for Nonlinear Equalizer in Coherent Optical Fiber Communications
IEEE Access, 2019 We propose and experimentally demonstrate a simple nonlinear equalizer based on functional-link neural network (FLNN). The nonlinear stochastic mapping enables FLNN to serve as a nonlinear network, so we construct an FLNN with the signals from the two ...

Incorporating Si into Sb2Se3: Tailoring Optical Phase Change Materials via Nanocomposites
Advanced Optical Materials, EarlyView.We study the structural, optical, and thermal effects of adding silicon to Sb2Se3 and demonstrate that the as‐deposited solid solution phase segregates after electro‐thermal switching, creating a nanocomposite with effective‐medium properties and a phase‐change response.

Thickness Dependence of Linear and Nonlinear Optical Properties of Multilayer 3R‐MoS2
Advanced Optical Materials, EarlyView.Thickness as a key design parameter for optimizing the nonlinear optical response of layered transition metal dichalcogenides (TMDs) materials is established. The demonstrated correlation between thickness, linear spectra, and harmonic generation efficiency provides a powerful framework for tailoring nonlinear performance.
