Hemicyanine Langmuir-Blodgett Films by Fourier Transform Infrared Spectroscopy and Second Harmonic Generation

The molecular orientation in amphiphilic hemicyanine Langmuir-Blodgett (LB) films has been studied quantitatively by Fourier transform infrared (FTIR) spectroscopy and second harmonic generation (SHG). From the analysis of transmission and reflection absorption (RA) spectra of FTIR, the tilt angles to the surface normal of the hydrocarbon chain axis and the chromophore of amphiphilic hemicyanin...

Theoretical analysis of phase-matched second-harmonic generation and optical parametric oscillation in birefringent semiconductor waveguides.

We analyze the phase-matching conditions for second-harmonic generation (SHG) and optical parametric oscillation (OPO) in birefringent nonlinear semiconductor waveguides and apply these results to the model system of ZnGeP2 on a GaP substrate. The analyses and numerical results show that phase matching can be achieved for OPO and SHG for reasonable guide thicknesses throughout much of the infra...

Efficient continuous wave second harmonic generation pumped at 1.55 microm in quasi-phase-matched AlGaAs waveguides.

We have fabricated quasi-phase-matched AlGaAs waveguides for continuous-wave second-harmonic generation (SHG) pumped around 1.55 microm. We find that the losses, which limit the conversion efficiency of this type of waveguide, are resulted from two corrugations--the initial template corrugation and the regrowth-induced domain-boundary corrugations. We are able to reduce the waveguide loss by im...

Quasi-phase matched second-harmonic generation through thermal poling in femtosecond laser-written glass waveguides.

Quasi-phase matched second-harmonic generation at 532 nm is demonstrated in a channel waveguide that is written in bulk fused silica using a femtosecond laser. The second-order nonlinear grating is fabricated using uniform thermal poling followed by periodic erasure inside an e-beam deposition system caused, by what we believe to be, x-rays. A SHG conversion efficiency of 2 x10(-5) %/W-cm(2) wa...

Large Area Fabrication of Semiconducting Phosphorene by Langmuir-Blodgett Assembly

Phosphorene is a recently new member of the family of two dimensional (2D) inorganic materials. Besides its synthesis it is of utmost importance to deposit this material as thin film in a way that represents a general applicability for 2D materials. Although a considerable number of solvent based methodologies have been developed for exfoliating black phosphorus, so far there are no reports on ...
