| Research Abstract |
The aim of this research project is to fabricate nonlinear two-dimensional (2D) photonic crystals (PhCs) by proposing a new 2D PhC structure that combines PhC functions and highly nonlinear optical materials. We reveal a direct relationship between the observed nonlinear optical responses and the corresponding photonic band structure, and we show experimental evidence that the performance of nonlinear optical applications such as the wavelength conversion and two-photon absorption devices are dramatically improved in this structure. Moreover, by using this physical enhancement mechanism, we demonstrate the high-efficiency, compact deep-ultraviolet (DUV) coherent wavelength conversion devices.
