Photonic generation of radio-frequency (RF) arbitrary microwave waveform with ultra-wide frequency tunable range based on a dispersion compensated optoelectronic oscillator (OEO) is proposed and experimentally demonstrated. Dispersion compensation scheme and specially designed fiber Bragg grating (FBG)-based Fabry–Perot (F-P) filters are employed in the OEO loop to realize a frequency tunable range of 3.5–45.4 GHz. An optimization process provided by the combination of an erbium-doped fiber amplifier (EDFA) and FBG is employed to improve the signal-to-noise ratio (SNR) of final RF signals. The generation of linear-frequency and phase-coded microwave waveforms, with a tunable carrier frequency ranging from 4 to 45 GHz and tuned chirping bandwidths or code rates, is experimentally demonstrated.

采用标准光荧光方法,在不加入探针或荧光、磷光染料的情况下,测量了具有56个和29个碱基的两种核酸单链样品的光致发光特性;该方法不会对样品造成破坏或污染。结果表明:当激发波长在310~410 nm之间时,能够在410~480 nm波长区间观测到样品明显的发光峰;两种样品的发光峰随着抽运波长的红移而红移,且发光峰的强度随激发波长的增加而先增强后减弱;具有两种不同碱基数和序列的核酸样品由于具有不同的电子能级结构而显示出了不同的光致发光特性,原理上可以用于甄别两种不同的核酸材料,有助于单链核酸样品的无损、无标记检
