Paper Abstract

The use of a shielded microstrip-configuration for polymer- based electro-optic modulators has the advantage over an open microstrip geometry that the modulator is pacified with respect to environmental conditions. We investigate such a shielded modulator numerically. Employing the Laplace equation the quasi-TEM field distribution is calculated and by employing Wheeler's incremental rule we determine the conductor loss due to the skin effect. We demonstrate that the use of a shield in combination with a buffer layer with a low dielectric constant yields the modulator insensitive to geometrical variations. For a modulator with a wide driving electrode the maximum bandwidth may be as high as 90 GHz.
