In this thesis, we study nonlinear optical properties of different periodic metallic nanoparticle arrays by using Nanosphere Lithography (NSL). Nonlinear optical properties would be enhanced because of surface plasma resonance which is genera

We demonstrated GaN-based photonic crystal (PC) nanobeam cavities by using the e-beam lithography and the suspended nanobeams were realized by focused-ion beam (FIB) milling. One resonant mode was clearly observed at 411.7 nm at 77K by optical pumpin
