In this work we present three speed optimized types of phototransistors built in a standard 180 nm CMOS technology without process modifications. An OPTO ASIC wafer consisting of a p + substrate with a low doped p epitaxial layer on top of it is used for the implementation. The phototransistors were produced in 40×40 μm 2 and 100×100 μm 2 sizes. A gain in responsivity of more than 13 and bandwi...

Designing optimal microstructures for solid oxide fuel cell (SOFC) electrodes is complicated due to the multitude of electro-chemo-physical phenomena taking place simultaneously that directly affect working conditions of a SOFC electrode and its performance. In this study, a new design paradigm is presented to obtain a balance between electrochemical sites in the form of triple phase boundary (...

In applications such as processor-memory interconnect, I/O networks, and router switch fabrics, an interconnection network must be scalable to thousands of high-bandwidth terminals while at the same time being economical in small configurations and robust in the presence of single-point faults. Emerging optical technology enables new topologies by allowing links to cover large distances but at ...

A new tunable fiber ring laser structure employing an Opto-VLSI processor and an erbium-doped fiber amplifier (EDFA) is reported. The Opto-VLSI processor is able to dynamically select and couple a waveband from the gain spectrum of the EDFA into a fiber ring, leading to a narrow-linewidth high-quality tunable laser output. Experimental results demonstrate a tunable fiber laser of linewidth 0.05...

In this research, HMX energy derivatives with different carbon-containing fullerenes in different temperature conditions were studied using density functional theory. For this purpose, the materials were first geometric optimized, then the thermodynamic parameters were calculated for all of them. Then, the process of changing the energy-dependent parameters such as specific heat capacity, entha...
