Electro‐optic modulators are key components in high bit‐rate optical transmissions. Decreasing the manufacturing cost without damage on performances is one of the most challenging issues for such components. We demonstrate that the electro‐optic modulators based on polymer are compatible with high bandwidth requirements. Indeed, according to the results obtained by numerical simulation and partly validated by experiments, with the via‐free GCPW‐MS‐GCPW electrodes proposed and analyzed in this article, the (400 MHz–67 GHz) bandwidth is achievable with electro‐optic modulators based on suitable polymers. These encouraging results are very useful for low‐cost mass production of polymer‐based electro‐optic modulators for a wide range of applications: digital and analogue high bit‐rate transmissions.© 2010 Wiley Periodicals, Inc.
