Mode manipulation in small microsphere systems

In this work we demonstrate the possibility of mode manipulation in systems of symmetric photonic molecules formed by placing several microspheres in contact. We observe photonic nanojets that reflect the symmetry of the photonic molecule, with 3 jets located at 120 degrees with respect to each other for the triangular molecule. We also present some results showing the coexistence of whispering gallery modes and nanojets in the same structure.
