Functional dielectric microstructure for photonic nanojet generation in reflection mode
Source abstract
Abstract
Abstract We first have performed direct experimental imaging of extended photonic nanojet generated in reflection mode by an array of aluminum oxide hemispheres. It was found that a primary photonic nanojet generated in transmission mode acts as an additional illumination source for the microparticle and interferes with the incident laser light forming a reflective photonic nanojet. The electromagnetic field distribution obtained experimentally is in good correlation with the numerically calculated one. We have developed an easy-to-implement technique for hemispherical dielectric microstructure formation and made a functional array of aluminum oxide microparticles for various optical applications. The obtained array was successfully used for photoluminescence enhancement and provides a new platform for various optical sensing measurements as well as high-resolution optical imaging.
