AbstractBarium titanate has recently been suggested as a possible candidate for use in periodically poled optical frequency conversion devices. We report refractive index measurements which are critical to periodically poled device designers and present quasi phase matching loci which can be used to design an optical parametric oscillator in periodically poled barium titanate

Cathodoluminescence Study

AbstractOrientation patterned (OP)-GaAs crystals show promise for use in tunable coherent light sources in the infrared (IR) and terahertz (THz). These structures consist of an alternating array of [001]/[00-1] oriented domains grown by hydride vapor phase epitaxy (HVPE). Material characteristics concerning the propagation losses, the crystal dimensions, and the grating size must be taken into account to implement optical devices for specific wavelength ranges and operating modes (CW or pulsed). The analysis of the main factors contributing to optical loss in the OP crystals is a crucial step toward their use in many promising applications. We present a cathodoluminescence study, where the main defects and their distribution over the OP-GaAs crystals are revealed, with special emphasis paid to the properties of the domain walls.

We report the results of an analysis of the functional capabilities of the KTP crystal and its isomorphs for nonlinear-optical frequency conversion of all types of interactions in the transparency range of the crystal. The possibility of implementing angle, wavelength (frequency), and temperature-noncritical phase matching is shown.
