Paper Abstract

In recent years, optical microresonators have been extensively investigated for possible applications in many different areas of research. In optical communications such resonators can be used for switching, filtering or multiplexing devices. Due to its high quality factors, spherical microresonators are of great interest for optical sensing. Here we will discuss the use of a microparticle array as a spectral sensing device. Especially the accuracy in wavelength determination for broad light sources are in the focus of this work. Beside this, results for two light sources with different wavelengths are given.
