Silicon-based electro-optic modulators contribute to easing the integration of high-speed and low-power consumption circuits for classical optical communications and data *** the plasma dispersion modulation,an alternative solution in silicon is to exploit the DC Kerr effect,which generates an equivalent linear electro-optical effect enabled by applying a large DC electric *** some theoretical and experimental studies have shown its existence in silicon,limited contributions relative to plasma dispersion have been achieved in high-speed modulation so *** paper presents high-speed optical modulation based on the DC Kerr effect in silicon PIN *** contributions of both plasma dispersion and Kerr effects have been analyzed in different waveguide configurations,and we demonstrated that the Kerr induced modulation is dominant when a high external DC electric field is applied in PIN ***-speed optical modulation response is analyzed,and eye diagrams up to 80 Gbit/s in NRZ format are obtained under a *** of 30 *** work paves the way to exploit the Kerr effect to generate high-speed Pockels-like optical modulation.

Flat electro-optical frequency combs play an important role in a wide range of applications,such as metrology,spectroscopy,or microwave *** a key technology for the integration of optical circuits,silicon photonics could benefit from on-chip,tunable,flat frequency comb *** this article,two different architectures based on silicon modulators are studied for this *** rely on a time to frequency conversion principle to shape the comb *** a numerical model of the silicon traveling-wave phase modulators,their driving schemes are optimized before their performances are simulated and compared.A total of nine lines could be obtained within a 2 dB flatness,with a line-spacing ranging from 0.1 to 7 *** this tunability is a major asset of electro-optical frequency combs,the effect of segmenting the phase modulators is finally investigated,showing that the flat lines spacing could be extended up to 39 GHz by this method.

对法国Douarnenez海湾拟庸鲽Pleuronectes platessa L.的食性进行了研究。依据一些常见的饵料指标,多毛类动物和双壳类动物为拟庸鲽的主要饵料;饵料双壳类动物贝壳厚度上限随着捕食鱼类的增长而提高。对拟庸鲽种内营养关系的对应分析表明,基本饵料的刚性和易捕性与捕食鱼类的体长关系密切;同时也揭示,某些鱼类食性综合指标并非总是有效的。
