a comprehensive study on the structural, electronic and nonlinear optical (nlo) properties of alumina nanostructures (al2o3)n with n = 2-5 belonging to the groups iii and vi dopants carried out by density functional theory. the nbo charges exhibit dopant atoms caused to the increasing charge transfer and introduces acceptor-donor model for nlo response of alumina nanostructures. under the influ...

We present an octave spanning supercontinuum (at the -35 dB level) ranging from 1100 nm to 2500 nm in InGaP photonic wire waveguides that are bonded to a silicon substrate and pumped by an ultrashort pulsed laser centered at 1550 nm. OCIS codes: (130.4310) Integrated optics, Nonlinear; (190.4400) Nonlinear optics, materials; (320.6629) Ultrafast optics, supercontinuum generation; (90.4390) Nonl...

Nonlinear Optics has continued to develop over the last few years at an extremely fast pace, with significant advances being reported in nonlinear optical metamaterials, optical signal processing, quantum optics, nonlinear optics at subwavelength scale, and biophotonics. These exciting new developments have generated significant potential for a broad spectrum of technological applications in wh...

: optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (pr) crystal are investigated. each crystal can be supported the spatial soliton, and at least one must be photovoltaic. the two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...
