Next-Generation Nonlinear Optical Materials for Applications in the Infrared
Abstract
This collaborative project investigates a new class of materials with exceptional nonlinear optical (NLO) second harmonic generation (SHG) properties functioning in the infrared region of the electromagnetic spectrum. The research aims to address this challenge by designing and growing high efficiency-high-power nonlinear optical (NLO) materials specifically for the infrared region. Low-dimensional structures with chalcogen elements can have higher second harmonic generation coefficients than corresponding three-dimensional (3D) structures at comparable optical bandgaps and as a result, much higher NLO optical responses. We propose three closely linked thrusts in this program. Thrust-A will develop the crystal growth techniques to grow very high-quality crystals of the high-performing materials in the alkali-metal selenoarsenates group and a full investigation of these crystals. Thrust-B we will have a more exploratory bent aiming at designing and discovering even better materials using the state-of-the-art chemical synthetic techniques and design and selection concepts that we have developed. Thurst C will focus on synergistic theoretical and experimental investigations to accelerate materials exploration.
