Abstract
It has been demonstrated that the nonlinear response of liquid crystalline materials can be beneficially modified through the introduction of a variety of dopant materials1,2,3. Novel wave-mixing phenomena, reduced energy density thresholds for limiting applications, and recently permanent holographic gratings2,3 have been observed for visible wavelength inputs. In this paper, we report the results of a series of experiments conducted on liquid crystal samples appropriately doped to respond to infrared wavelengths (specifically 1320nm), where initial measurements show promise for a variety of applications in infrared processing and communications systems.
