Abstract
A wide-bandwidth Mach-Zehnder traveling-wave electro-optic modulator w as realized using novel low-loss slow-wave coplanar strips on a GaAs/A lGaAs substrate. Microwave characteristics of the device were measured up to 40 GHz. The microwave loss at 40 GHz is 7 dB/cm, and a phase ve locity of 8.15 cm/ns was obtained. The device demonstrates a half-wave voltage of 20.5 V and an extinction ratio of 9.5 dB. A flat large-sig nal modulation response up to 22 GHz was measured. (C) 1998 John Wiley & Sons, Inc.
