Broadband wavelength switching and signal regeneration experiments with 10 Gbit=s return-to-zero signals using a photocurrent-driven wavelength converter (PD-WC) are presented. For wavelength switching using an ideal input signal to the PD-WC, the device generates up to þ3.7 dB facet to facet gain and shows < 1 dB power penalty in bit error rate measurements. For wavelength switching with a deg...
In this paper we give an overview of tasks, models and mixed-signal simulation tools to support design of digitally controlled switching power supplies where the digital controller is implemented in a dedicated FPGA or ASIC. Mixed-signal simulation models of a digitally controlled switching converter based on Matlab/Simulink and HDL/Spice simulation tools are presented. The models are used in t...
An external redox signal delivered by ascorbic acid was used to trigger membrane translocation in a synthetic transduction system.
As the demand for high-speed communication both in wired and in wireless systems increases, the optical fiber communication systems have been developed in such a way that the information transmission capacity through an optical fiber exceeds terabits per second. As the data speed increases, the packet switching network is expected to advance from electronic packet switching to all-optical packe...
There is a growing need for routers to support multicast and broadcast applications such as war gaming, teleconferencing and web casting. Using the natural parallelism of optics in a switching core, high-performance routers that are efficient for heavily multicast/broadcast traffic can be implemented. A broadcast and select based optical switching core can handle efficiently multicast/broadcast...
We present the design, fabrication, and characterization of a MEMS-based 3-bit Digital-to-Analog Converter (DAC) that allows generation large displacements. The DAC consists electrostatic bending-plate actuators are connected to mechanical amplifier (mechAMP), enabling amplification output displacement. Based on parallel binary-encoded voltage signal, displacement system can be controlled in an...
