Characteristics of optical waveguides made by electric-field-assisted K(+)-ion exchange
Abstract:
Planar optical waveguides were fabricated by using an electric-field-assisted potassium-ion exchange in soda-lime glass substrates. Mode index measurements for both the TE and TM modes were made for the purpose of establishing formulas for the effective diffusion constant, guide depth, and refractive-index change, given the electric field, the diffusion temperature, and the time. The index profile could be accurately modeled by a modified Fermi function, with significant improvement over the step-index model.

Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium, μ.
Furthermore, the...
