Abstract
Bottle and spherical micro-resonators will be presented. For bottle microresonators, we will present the Surface Nanoscale Axial Photonics (SNAP) platform [1,2], an approach for description and several examples of SNAP delay lines. For spherical microresonators, we will present optoplasmonic sensors allowing to detect single ions and even movements of molecular sides [3].
