Even to a casual observer it should be clear that interest in phenomena lying at the interface between photonics and nano-science is undergoing an explosion. The material—Zinc Oxide (ZnO), has attracted much interest because of its unique optical properties and potential use in photonics and nano-technologies. The bulk of our studies involve various properties of ZnO film, especially their nonlinear optical response, and some practical applications that can follow from such studies. The ZnO films were deposited by reactive sputtering and optically characterized. The effects of some <italic>in situ </italic> and <italic>ex situ</italic> processes, such as substrate selection, heating during film growth and post-deposition annealing, on the properties of the films are presented. Second harmonic (SH) generation from ZnO crystals and films was studied. The evolution of the SH signal with film thickness is particularly interesting. Computational models were developed to study the enhanced nonlinear response and optical bistable effect from ZnO in conjunction with the electrical field enhancement resulting from either the attenuated total reflection effect or resonant waveguide coupling. Enhanced electrical fields in silver films were obtained experimentally in both visible and infrared region. Some applications associated with this electrical field enhancement were simulated. In particular enhanced photoluminescence in a ZnO waveguide was observed and allowed us to achieve ultraviolet (UV) lasing with ZnO thin films. In addition, the effect of magnesium doping in ZnO was studied. In a separate study a fast optical switch based on a self-assembled chromophoric film was demonstrated. Such switches may find applications in optical communications.Subjects--Topical Terms:
