Abstract
Official abstract text for this publication.
Electro-optical modulators and methods of fabrication are disclosed. An electro-optical modulator includes a Mach-Zehnder interferometer formed in a substrate removed semiconductor layer and a coplanar waveguide. Signals from the coplanar waveguide are capacitively coupled to the Mach-Zehnder interferometer through first and second dielectric layers having strong dielectric constant dispersion.
First claim
Opening claim text (preview).
It is claimed: 1. An electro-optical modulator comprising: a Mach-Zehnder interferometer formed in a substrate removed semiconductor layer; and a coplanar waveguide, wherein signals from the coplanar waveguide are capacitively coupled to the Mach-Zehnder interferometer through first and second dielectric layers having strong dielectric constant dispersion. 2. The electro-optical modulator of claim 1 , wherein the dielectric layers have an index of refrac…
