Wideband Electroabsorption Modulator for Analog Applications

Abstract

There were two main technical objectives of this program with respect to the investigation of the high speed waveguide electroabsorption (EA) modulator, namely: (1) Design and fabrication of a waveguide modulator with a widened optical waveguide for easy packaging and lower insertion loss, and (2) interfacing with Infotonics for their fiber packaging effort of the modulator. In addition, an examination of the limits to Radio Frequency (RF) link gain, noise figure and spurious free dynamic range (SFDR) of the EA modulator was accomplished. This program produced the following accomplishments: 1) Finished a design for the modulator with large optical waveguide to improve the coupling in materials structure of either bulk InGaAsP or multiple quantum wells. The design has been fabricated at UCSD and repeated at a commercial foundry. 2) Examined the limits of RF link gain, noise figure and SFDR of EA modulators.
