Abstract In the present work, a high-speed optical encoder is proposed based on two-dimensional photonic crystal ring resonator (2D-PCRR) using coupled mode theory and resonance effect. Square shaped ring resonator, couplings rods and several waveguides have been utilized in the proposed structure. Silicon rods in air structure has been designed with rod radius of 0.1a and lattice constant 0.540 nm. The photonic band gap is being calculated using plane wave expansion method and finite-difference-time-domain method to analyze the performance characteristics of optical encoder like: transmission spectra, electric field view, contrast ratio, delay time, response time etc. The operating wavelength of structure is 1550 nm, to perform encoder operation where only one input port is activated at a time while other input ports are inactivated and accordingly equivalent binary encoded signal is produced at output ports. The proposed encoder is designed with fast response time 222.76 fs, high data rate of 4.48 Tbps and ultra-compact size of 140.84µm2. Hence the proposed device is suitable for high-speed optical computation, photonic integrated devices and high speed optical integrated circuits.

Communication between a sink node and a PC can constitute a bottleneck for high data rate applications of wireless sensor networks (WSNs) including, but not limited to, structural health monitoring, condition monitoring, wireless surveillance and patient health monitoring. In this paper, we evaluate four different data acquisition alternatives for data-intensive WSN applications. We will concentrate especially on optimizing UART (universal asynchronous receiver transmitter) communication in conjunction with WSN applications. Furthermore, we propose a new method for sink node to PC communication, which is based on using a USB-connected data acquisition (DAQ) board that samples the node external I/O. This method can provide an efficient solution to transfer data from the sink node to PC at a reasonable cost. Wireless sink node converts the data received from the network into analog signal levels, which are sampled through the DAQ board connected to a PC, and the original data is reconstructed offline. Tests on a wooden bridge built to scale with six wireless sensor nodes and a sink node show that with the proposed method it is possible to collect the data from the network and transfer them onto the PC significantly faster than with the 115.2 kbps UART communication regularly used in WSN applications.

Li-Fi system is a recent and brilliant technology which is utilized visible light as a medium for multimedia data transmission. In Li-Fi communication system, transfers data in the form of light signals as an alternative of Wi-Fi. The Li-Fi technology supports transmission of multimedia data in the way of light particles by sending the multimedia data via LED bulbs that make changes in faster transmission. The Li-Fi with hardware and software model creation with many parameters that must be considered while implementing a Li-Fi based transmission system prototype which is high data rate, distance and the LOS. These parameters are taken for major component when modelling a Light Fidelity system. The main problems in the implementation of an improved data rate at low network coverage and powerless location multi point VLC system and solar component are the range and cost effective model. The VLC source component and destination component must be compatible for high data rate. The conventional lighting technique in communication feels from intrusion and maximum delay possibilities. Solution for the above light based transmission problems in implementation; VLC is a preferred communication model because of its maximum throughput and secure transmission from light particles. The proposed Multi Point Visible Light Communication Li-Fi model provides high-speed communication to achieve better capacity, efficiency, and availability at low network coverage than existing lighting technology
