چکیده

Second-harmonic generation using the type-II polarization configuration is demonstrated in quasi-phase-matched GaAs radicalAlGaAs superlattice waveguides. Phase-matching wavelengths and conversion efficiencies were determined for several quasi-phase-matching periods using 1.9 ps pulses. Saturation effects at high input power were concluded to be the result of third-order nonlinear effects.

Quasi phase matching in GaAs--AlAs superlattice waveguides through bandgap tuning by use of quantum-well intermixing.

We report the observation of second-harmonic generation by type I quasi phase matching in a GaAs-AlAs superlattice waveguide. Quasi phase matching was achieved through modulation of the nonlinear coefficient chi((2))(zxy), which we realized by periodically tuning the superlattice bandgap. Second-harmonic generation was demonstrated for fundamental wavelengths from 1480 to 1520 nm, from the thir...

Odd waveguide mode quasi-phase matching with angled and staggered gratings.

Angled and staggered gratings are used for quasi-phase matching of antisymmetric TM(10) modes in periodically poled lithium niobate waveguides with high efficiency. Control of the symmetry of the nonlinear coefficient d adds a new degree of freedom in the choice of which waveguide modes will interact in a quasi-phase-matched device.

Second harmonic generation in nano-structured thin-film lithium niobate waveguides.

Integrated thin-film lithium niobate platform has recently emerged as a promising candidate for next-generation, high-efficiency wavelength conversion systems that allow dense packaging and mass-production. Here we demonstrate efficient, phase-matched second harmonic generation in lithographically-defined thin-film lithium niobate waveguides with sub-micron dimensions. Both modal phase matching...

Broadening of the second-harmonic phase-matching bandwidth in type II periodically poled KTP.

We have theoretically demonstrated type II broadband second-harmonic generation (SHG) based on a quasi-phase-matching (QPM) configuration in periodically poled KTP (PPKTP). The wavelength dependence of QPM grating periods at different temperatures of 5 degrees C, 25 degrees C, and 45 degrees C is calculated with the crystal length of 1 cm. We find a very wide bandwidth, as large as 42.6 nm, of ...

Band gap gratings using quantum well intermixing for quasi-phase-matching

In this work, the spatial resolution of two quantum well intermixing processes has been obtained using spatially resolved photoluminescence. The processes investigated are impurity-free vacancy disordering using SiO2/SiO2:P caps and sputtered silica induced intermixing. These studies aimed to choose a suitable intermixing technology to realize the band gap gratings for domain disordering quasi-...
