Incorporation of Highly Dispersed Gold Nanoparticles into the Pore Channels of Mesoporous Silica Thin Films and their Ultrafast Nonlinear Optical Response

Thermal Penetration of Gold Nanoparticles into Silicon Dioxide

“…polymers, silicon dioxide, oxynitride layers, etc.) for creation of the nanocomposite films, which are of importance because of their unusual nonlinear optical and electrical properties [7,8]. Evidently, the properties of nanocomposites will depend on the size, density, and the position of Au NPs [9].…”

Giant optical nonlinearity of silver-doped silicon thin film at low power input: laser-triggered cluster resonance

“…In the past times, third-order optical nonlinear properties, such as the Kerr effect and two-photon absorption, have been extensively studied with a variety of metal-doped composites [1][2][3][4][5][6][7][8]. With different doping elements and background matrix, the composites can be configured to pos-sess well pronounced nonlinear effects with fast time responses [1][2][3][4][5][6][7][8].…”

“…With different doping elements and background matrix, the composites can be configured to pos-sess well pronounced nonlinear effects with fast time responses [1][2][3][4][5][6][7][8]. Such properties are widely demanded particularly in the recently and rapidly developed photonic and optical communication devices, such as optical correlators, phase conjugators, high density optical storages, and compact all-optical switches.…”

“…Such properties are widely demanded particularly in the recently and rapidly developed photonic and optical communication devices, such as optical correlators, phase conjugators, high density optical storages, and compact all-optical switches. The composites reported to bear high nonlinear responses include among others metallic nanoparticle-doped glasses or other dielectrics, such as TiO 2 capped Au nanoparticle films, Ag doped BaO and Bi 2 O 3 thin films [1][2][3][4][5][6][7][8].…”

“…However, a well-known restriction for the composites to find applications in compact optical devices is the requirement for high power inputs. Except for some bismuth thin films in molten states [9], ultra high intensity laser pulses are usually needed to trigger significant nonlinear yields [1][2][3][4][5][6][7][8]. Therefore, a plausible improvement would be to reduce the power level of the input.…”
