چکیده

рассмотрены вопросы высокоскоростной коммутации сигналов в оптической шине передачи данных на печатной плате. Для создания оптических коммутаторов предлагается использовать каскады волноводных интерферометров Маха–Цендера основе электрооптических полимеров с фторсодержащими хромофорами боковой цепи, способными изменять показатель преломления под действием приложенного электрического поля. Такие коммутаторы обладают высоким быстродействием и обеспечивают частоты переключения уровне 100 ГГц. Предложен подход к формированию одномодовых волноводов полимерах, основанный лазерном фотоосветлении хромофоров, которое сопровождается уменьшением показателя полимера излучения видимого диапазона. the study considers high-speed switching in an optical bus on a printed circuit board (PCB). We proposed to use cascades of Mach–Zehnder waveguide interferometers build switches. The are made electro-optical polymers with fluorine-containing chromophores side chain. substance changes its refractive index when electric field is applied. Such switches fast: frequency up GHz. authors also approach manufacturing single-mode waveguides and polymer using laser photo-clarification chromophores. Visible light decreases decrease polymer.

Universal Serial Bus Signal Integrity Analysis for High - Speed Signaling

The Universal Serial Bus transmits differential data over twisted-pair cables originally designed for signaling at 12Mbit/s. Because of the recent specification of a 480Mbit/s signaling speed with the existing cabling, the high frequency behavior and temporal response of these cables is of interest. In this work, twoand threedimensional field solvers are used to characterize the field behavior ...

High-Speed PCB Design Considerations

The backplane is the physical interconnection where typically all electrical modules of a system converge. Complex systems rely on the wires, traces, and connectors of the backplane to handle large amounts of data at high speed. The communication between the various backplane modules depends on the inherent electrical characteristics such as impedance, capacitance, and inductance derived from c...

Package and PCB Solutions for High-Speed Data Link Applications

Continual increase in high-speed transfer rates is essential in today's world in order to keep up with Moor's law scaling and to meet application demands. This increase in information transfer rates is essentially limited by the bandwidth of the communication channel. Channel loss, signal crosstalk, and power integrity are the important factors affecting the bandwidth of the channel and must be...
