We consider the nonlinear Schrodinger–Maxwell–Bloch (NLS–MB) equation with variable coefficients. We construct the Lax pair for the NLS–MB system through AKNS formalism. We derived the two-soliton solution using the Darboux transformation. Finally we demonstrate the nonlinear tunneling of two solitons through dispersion and the nonlinear barrier or well. Our result shows that solitons can be compressed through the tunneling barrier or well with exponential decay for the special choice of variable coefficients.

We obtain the bright similariton solutions for generalized inhomogeneous nonlinear Schrödinger equation (GINLSE) which governs the pulse propagation in a tapered graded index diffraction decreasing waveguide (DDW). The exact solutions have been worked out by employing similarity transformations which involve the mapping of the GINLSE to standard NLSE for the certain conditions of the parameters. By making use of the exact analytical solutions, we have investigated the dynamical behavior of optical similariton pairs and have suggested the methods to control them as they propagate through DDW. Moreover, pulse width of similariton is controlled through various profiles. These results are helpful to understand the similaritons in DDW and can be potentially useful for future experiments in optical communications which involve optical amplifiers and long-haul telecommunication networks.

We propose high-sensitive based temperature sensor using photonic crystal fiber(PCF). The liquid filled at the center and its corresponding low index surrounding region is used for transferring the energy to detect the temperature changes. The air hole of the PCF is applied by temperature sensitive liquid which supports central core mode (high index core). Six cores are created and filled by silica with absence of air holes in the second layer of central holes. So it can be act as defect modes (low index core). In our proposed PCF with PML, the temperature sensitivity −2.0nm/°C was achieved with the detecting range of 20°C to 80°C. Moreover, the paper discusses the dispersion curve over the region 1.24μm to 1.44μm.
