Abstract
A theoretical formulation of coherent optical tunneling and the subseq uent exchange of electromagnetic energy between two Mie-sized microsph eres is presented. The coupled-mode theory of Debye potentials is used . A useful analytical expression for the self- and mutual-coupling coe fficients that are involved in the time-evolved coupled-mode equations is derived under a weakly coupling approximation. Sample numerical re sults are shown for coupling between identical spheres.
