We describe recent theoretical and experimental studies of polarization and spatial information recovery by modal dispersal and phase conjugation. We discuss the fidelity of this phase-conjugation process as a function of input-beam launching conditions. We also describe several new applications of the scheme which involve correction of nonreciprocal polarization distortions, correction of loss...

background:  wi-fi allows electronic devices such as laptops to exchange data or connect to a network resource. the main goal of this study was to assess the bioeffects of short term exposure to 2.4 ghz microwave radiation emitted from a common wi-fi router on sperm quality. materials and methods: male wistar rats were divided into 7 groups; i, sham exposed 4 h/day for 7days at 30 cm from the r...

Perkembangan teknologi jaringan dari waktu ke semakin pesat, oleh karena itu diperlukan akses yang aman atau secure. Dengan banyaknya jaringan, maka akan banyak pula peluang terjadinya kejahatan di dalam tersebut. Penelitian ini menggunakan metode penetration testing bertujuan untuk menganalisis celah keamanan pada login router Mikrotik SMKN 2 Sumbawa. Dalam melakukan trial attack, penelitian B...

We briefly review a recent technological development for simultaneous optical stimulation and optical imaging of activation in cardiac tissue. Such alloptical system for interrogation of cardiac electrophysiology can facilitate the study of arrhythmias and the development of a new generation of optical pacemakers. Key elements in the system included the biological integration of light-sensitive...

In this paper, we focus on issues of routing information exchange in large-scale WDM networks. Specifically, we present two schemes, i.e., direct routing information exchange and routing information broker. We then analyze and compare these schemes based on their scalability, complexity and communication overhead. Finally, on examples of metro alloptical networks interconnected over an all-opti...

increasing the number of cores integrated on a chip and the problems of system on chips caused to emerge networks on chips. nocs have features such as scalability and high performance. nocs architecture provides communication infrastructure and in this way, the blocks were produced that their communication with each other made noc. due to increasing number of cores, the placement of the cores i...

we design and simulate a five-port optical router, which is composed of twenty mach-zehnder-based switching elements and twelve waveguide crossings for use in integrated photonic interconnection networks. we simulated and analyzed the operation of the proposed optical router from the aspects of insertion loss, power budget, q-factor and the minimum bit error ratio by use of optisystem simulator...
