    Abstract: Optical signal is the best suitable one for data processing and digital signal communication for its inherent parallelism and tremendous operational speed. Conventional electronic or optoelectronic devices are unable to fulfill this due to less speed and time delay. In the case of perfect electronic flip-flop, at the time of switching turned ON, th...

    Abstract: Many different photovoltaic technologies are being developed for better solar energy conversion. Until now, crystalline Si solar cell represents the dominant photovoltaic technology with a market share of more than 94% with an efficiency between (15%-20%). Organic-inorganic halide Perovskite Solar Cell (PSC) has emerged as the most promising candid... Show More

    Abstract: In this work, we establish the Conditions that must satisfy the characteristic coefficients of the nonlinear and flattened dispersive optical fiber so that certain classes of solitary waves propagate there with fewer fluctuations. Once the conditions are established, we determine the exact solutions as well as the corresponding nonlinear partial di... Show More
