New Organic Salts for Electro-optics and THz Generation

Organic materials with high second order optical nonlinearities have attracted a lot of attention because of their potential for optical frequency conversion, THz generation, electro-optical and integrated optics applications. However, the theoretical limits for the macroscopic second-order nonlinearities in organic crystals are still far from being achieved. In addition, the growth of high quality nonlinear optical bulk or thin film organic crystals such as DAST remains a big challenge.
