Abstract In this study, ZnO nanorods (ZnONR) were directly grown on carbon fiber paper (CFP), followed by the uniform chemical deposition of CuO nanowires (CuONW) and subsequent hydrothermal synthesis Ag nanoparticles (AgNP) to form ternary composite electrode AgNP‐CuONW/ZnONR@CFP. When prepared electrodes investigated as a non‐enzyme biosensor, two distinct separated differential pulse voltammetric peaks for puerarin (PU) daidzein (DAI) observed, indicating that simultaneous selective...
We demonstrate second-harmonic generation with ultranarrow resonances in hybrid plasmon-fiber cavities, formed by depositing single-crystalline gold nanorods onto the surface of tapered microfibers diameters range 1.7-1.8 μm. The localized plasmon mode single nanorod efficiently couples a whispering gallery fiber, resulting very narrow resonance high quality factor Q up to 250. When illuminated tunable 100 fs laser, sharp SHG peak narrower than half spectral width impinging laser emerges,...
A high-quality plasmon–fiber cavity in a doubly resonant configuration can exhibit second-harmonic generation (SHG) with over 5 orders of magnitude enhancement compared to gold nanoparticles on fused silica substrate. Through coupling fiber the proper diameter, (Q ≈ 160) resonance be achieved combination single nanoparticle. In classical picture, where incident electric field travels coherently Q times around during nonlinear process, high coupled mode aids highly efficient SHG. We...
Based on a digital micromirror device (DMD) processor as the multi-wavelength narrow-band tunable filter, we demonstrate multi-port fiber laser through experiments. The key property of this is that any lasing wavelength channel from arbitrary output port can be switched independently over whole C-band, which only driven by single DMD chip flexibly. All outputs display an excellent tuning capacity and high consistency in C-band with 0.02 nm linewidth, 0.055 step, side-mode suppression ratio...
We investigate the multiphoton photoluminescence (MPPL) characteristics of bare and palladium-capped gold nanobipyramid particles deposited on microfibers with diameters around 1.7 μm. A broad luminescence emission two evident peaks is detected when coupled are illuminated a femtosecond laser. By employing multiple peak Lorentz fitting to each PL spectrum performing nonlinear order analysis excitation power-dependent measurement, we come conclusion that four-photon (4PPL) at 520 nm...
Frequency-tunable microwave signal generation is proposed and experimentally demonstrated with a dual-wavelength single-longitudinal-mode (SLM) erbium-doped fiber ring laser based on digital Opto-DMD processor four-wave mixing (FWM) in high-nonlinear photonic crystal (PCF). The PCF employed for the of FWM to obtain stable uniform oscillation. Two different short passive sub-ring cavities main cavity serve as mode filters make SLM lasing. two lasing wavelengths are electronically selected by...
A high stable wavelength-tunable fiber laser is experimentally demonstrated by using a digital-micromirror-device (DMD) processor and polarization-maintaining erbium-doped amplifier (EDFA).The electronic-addressed DMD able to select couple waveband from of the EDFA back into ring generate narrow line-width output. The tunable shows 0.02 nm, tuning step 0.08 nm over c-band side mode suppression ratio (SMSR) greater than 50 dB. output power uniformity 0.01 mW achieved automatic control (APC)...
