All-optically induced quasi phase matching in SiN waveguides for second harmonic generation enhancement

Tobias Kippenberg, Camille Sophie Brès, Davide Grassani, Martin Hubert Peter Pfeiffer, Svyatoslav Kharitonov, Adrien Billat

We report more than 30dB second harmonic generation enhancement in SiN waveguide by all-optical writing of a persistent χ(2) grating. Phase matching peaks are observed for different writing wavelengths. ...

Orientation Dependence of Plasmonically Enhanced Spontaneous Emission

Olivier Martin

We computationally explore how the orientation of dipolar emitters placed near plasmonic nanostructures affects their radiative enhancement and spontaneous emission rate. We demonstrate that the expressions for these quantities show a subtle dependence on ...

Design, simulation, and quality evaluation of micro-optical freeform beam shapers at different illumination conditions

Hans Peter Herzig, Daniel Infante Gómez

A design method to generate thin micro-optical freeform (MOF) beam shapers by clipping or wrapping an original and much thicker freeform surface is provided. MOF elements are situated at the border between refractive and diffractive optical elements. The i ...

Beyond Vibrationally Mediated Electron Transfer: Coherent Phenomena Induced by Ultrafast Charge Separation

Jacques-Edouard Moser

Wave packet propagation succeeding electron transfer (ET) from alizarin dye molecules into the nanocrystalline TiO2 semiconductor has been studied by ultrafast transient absorption spectroscopy. Because of the ultrafast time scale of the ET reaction of abo ...

A New Perspective in the Use of FeOx-TiO2 Photocatalytic Films: Indole Degradation in the Absence of Fe-Leaching

César Pulgarin, Juan Kiwi, Sami Rtimi

The study addresses the degradation of Indole under low intensity solar simulated light. The first evidence is presented for sputtered films degrading Indole at the solid-air interface. The co-sputtering of FeOx-TiO2 on polyethylene (PE) leads to an accele ...

Characterization and modeling of microstructured chalcogenide fibers for efficient mid-infrared wavelength conversion

Camille Sophie Brès, Davide Grassani, Svyatoslav Kharitonov, Adrien Billat, Sida Xing

We experimentally demonstrate wavelength conversion in the 2 μm region by four-wave mixing in an AsSe and a GeAsSe chalcogenide photonic crystal fibers. A maximum conversion efficiency of −25.4 dB is measured for 112 mW of coupled continuous wave pump in a ...

Versatile High Repetition Rate 2-μm Pulsed Source Based on Wideband Parametric Conversion

Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette

We report an all-fiber pulsed source based on parametric conversion followed by thulium amplification able to deliver picosecond pulses at a repetition rate selectable between 2 and 5 GHz, of which central wavelength can be freely selected in the 2-μm regi ...

Maximizing Nonlinear Optical Conversion in Plasmonic Nanoparticles through Ideal Absorption of Light

Olivier Martin, Jérémy Butet, Shourya Dutta Gupta, Kuang-Yu Yang

The optimization of nonlinear optical processes in plasmonic structures is important for the design of efficient nonlinear nanosources of light. Considering the simple case of spherical nanoparticles, we clearly identify the most efficient channel for seco ...
