Abstract

See full text

An electro-absorption modulator (EAM) is configured to include an on-chip AC ground plane that is used to terminate the high frequency RF input signal within the chip itself. This on-chip ground termination of the modulation input signal improves the frequency response of the EAM, which is an important feature when the EAM needs to support data rates in excess of 50 Gbd. By virtue of using an on-chip ground for the very high frequency signal content, it is possible to use less expensive off-chip components to address the lower frequency range of the data signal (i.e., for frequencies less than about 1 GHz).
