Abstract
A method of making a microresonator device includes the steps of providing at least a first substrate and providing a waveguide integrated on the substrate. The waveguide includes a core and a metal cladding layer on at least part of one boundary of the core. Another step is positioning a microresonator so that it is in an optically coupling relationship with the waveguide.
