    Ultrafast Probe of Carrier Diffusion and Nongeminate Processes in a Single CdSSe Nanowire by Peter S. Eldridge, Jolie C. Blake, Lars Gundlach

    Published 2015-01-01
    “…The time-resolved emission exhibits a dependence on excitation fluence, with the onset of the emission varying on the picosecond time scale with increasing laser power. By fitting the emission to a model for amplified spontaneous emission (ASE), we are able to extract the nonradiative carrier recombination lifetime and nongeminate recombination constant. …”

    Existence of positive solutions for generalized quasilinear Schrödinger equations with Sobolev critical growth by Nian Zhang, Chuchu Liang

    Published 2024-08-01
    “…In this paper, we are devoted to establishing that the existence of positive solutions for a class of generalized quasilinear elliptic equations in $\mathbb{R}^{N}$ with Sobolev critical growth, which have appeared from plasma physics, as well as high-power ultrashort laser in matter. To begin, by changing the variable, quasilinear equations are transformed into semilinear equations. …”

    A novel low cost bidirectional transmission coherent passive optical network system by Shunli QIU, Yi YANG, Rong HU

    Published 2016-07-01
    “…Based on the coherent optical reception technology,a cost-effective structure for the optical network unit (ONU) transceivers in ultra-dense wavelength division multiplexing passive optical network using a single directly modulated laser (DML)was proposed.To reduce the number of required light sources,only one DML was used in both upstream and downstream links.By experimental investigations,the impacts of driving amplitude and bias current on DML's performance were analyzed.Meanwhile,the impact of frequency spacing between upstream and downstream signal and the Rayleigh backscattering interference on system performance were investigated.The method has better performance of system receiving and can effectively reduce the cost and complexity of coherent passive optical network system.…”
