However, it is complicated to determine the multi-objective functions (gain, bandwidth and flatness), multi decision variables and multiple global solutions. Optimization works only considered undepleted pump configuration or pump depletion but without fiber loss. Recently, a machine learning approach was applied to design a Raman amplifier. Thus, this study intends to design a desired dual-pump FOPA gain utilizing an artificial neural network (ANN) to predict pump powers and pump wavelength by considering pump depletion and fiber loss. First of all, the FOPA training gain data were obtained through the 6-wave model and supplied into the ANN to learn the relation between the gains with their pump wavelengths and pump powers. Once the smallest mean square error (MSE) between input and target was obtained, the ANN model was saved. The ANN model can be used to predict the desired pump wavelengths and pump powers if the desired gain is given. The desired gains of constant values from 10 to 45 dB over 1540-1589 nm for optical communication are predicted very well with mean absolute error (MAE) of 1 dB variations.

As a result, there is a need for an alternative technology that may provide revolutionary results. The quantum-dot cellular automaton is now widely regarded as a viable alternative to complementary metal-oxide-semiconductor technology. This paper demonstrates a new circuit for constructing a quantum-dot cellular automaton-based programmable logic array. The programmable logic array is a promising, standard, and fully programmable architecture that can use redundancy to make circuits with nanoscale feature sizes more practical. The comparisons based on cell number, size, and clock phases were made between the proposed circuit and previous ones using the QCADesigner. These comparisons verified the efficiency of the proposed design. The suggested programmable logic array circuit consists of 26 cells and occupies 0.04 mu m(2). In addition, the quantum cost of this circuit is 2.08, and the area delay is 0.08.

The localized solutions are obtained in terms of the hypergeometric functions F(a, b, c; z). The dynamics of these resonant states and their control, for PT potential, is discussed employing isospectral Hamiltonian technique, which is analytically tractable.
