All-optical logic and algebraic operations may now be performed using a QD-SOA-based gate using a quantum-dot semiconductor optical amplifier (QD-SOA). This is utilized in photonic processor for high-speed data transfer which relies on all optical logic gates. The nonlinear property of the SoA has recently been used to demonstrate high-speed all-optical logic gates. The QD SOA technology that has evolved in recent years has made a superior signal processing device available in the communication spectrum. Devices of this kind have been demonstrated experimentally to have a high saturation output power and low noise, fast carrier relaxation between QD energy levels, and a reduced impact on carrier heating gain and phase recovery. In this paper, a new technique for enhancing signal transmission quality using ultrafast nonlinear interferometer-based all-optical logical operations was proposed. For this purpose, a pair of QD-SOAs is incorporated into an interferometer. The optical logic XNOR gate-based model was demonstrated with the help of a pseudo-multilinear binary sequence (PMLBS) generator. The impact of the peak data power as well as of the QD-SOAs current density and QD-SOAs length on the ER and Q-factor of the switching outcome are explored and assessed using numerical simulation. The model’s findings on optical logic gates and PMLBS production imply that this system may generate data at speeds of up to 250 Gbps while maintaining high output efficiency.</em></p> P.

It has been observed that the country’s security is primarily dependent on the soldiers’ unit or army force. In battleground or clandestine operations, troop communication and health monitoring are critical. Technologies such as walkie-talkies or GSM modules have often been used for communication and tracking soldiers’ movements on the battlefield in recent decades. These studies suggest an effective way to use an electronic device that can transform sign language hand gestures into speech to allow effective interaction among soldiers to adapt to the current technology. The technology involves converting signals from hand into voice signals, which can subsequently be transmitted via wireless devices. The ‘Hand Talk’ gloves are regular driving gloves with electrode sensors built in. The sensors produce a stream of data that varies depending on the finger’s flexibility. The sensor’s output is converted to digital and processed with an Arduino, after which it reacts to voice commands over Zigbee. It is also necessary for the control station to know the health condition of soldiers along with the location on the battlefield. To track the current situation, the device is mounted in a hand glove and data can be transferred to the base station with the help of IoT (internet of things). The main motivation for this research is to know how to build effective communication between soldiers along with their health monitoring system. </em></p> Kalpavi C.Y. Karthik G.
