With the DURIP fund, we acquire a glass processing station to enhance our capabilities to achieve ultra-high performance photonic resonators and fiber structures with specially designed nanomicro features for building optical sensors with lower detection limits and detection resolution beyond what can be achieved in our group and other labs in the field. The equipment immensely contributes to our research project funded by PECASE supported by DoD-ARO under the contractgrant number W911NF-12-1-0026 on high performance optical sensors. The multipurpose glass processing station also allows us to develop and fabricate novel photonic devices for the control of light and energy flow. Specifically, we fabricate a novel sound wave sensor that can respond to particular characteristic frequency depending on the specific sizes and shapes of a fiber taper optical waveguide. We also design and fabricate a bottle-shaped resonator from an optical fiber. Compared with WGM resonators in other shapes, such as microspheres and microtoroids, bottle resonators are more practical as a sensor for real-time monitoring of dynamic processes in micronanoscale in non-fluorescent solution, which might help provide information not available before using conventional measurement.
