Self-focusing effect via Kerr nonlinearity is observed in periodically poled lithium niobate (PPLN) waveguide arrays for......

We report the transformation of a linear electro-optically tunable non-phase-matched second-order nonlinear process into......

We report a universal approach based on the surface plasmon resonances (SPRs) attained in filamentation in water doped w......

We demonstrate that the filamentation process is strongly influenced by the polarization state of the driver laser. When......
