Chemical bonding and atomic structure of Rb+ exchanged KTiOPO4 waveguides probed by micro-Raman spectroscopy
Abstract
Channel waveguides of Rb+ exchanged single-crystal KTiOPO4 were studied by micro-Raman spectroscopy. Rb+ exchange causes a disruption of the long-range translational (crystal) symmetry of the lattice and a tilting of the TiO6 octahedra. The ability to nondestructively map the chemical and physical structure related to the optical properties of channel waveguides is demonstrated.© 1995 American Institute of Physics.
