Abstract
An electroabsorption device includes an optical waveguide having an input portion with a first optical confinement characteristic. A first electroabsorption region is formed along the optical waveguide having a first optimized optical mode confinement characteristic. A second electroabsorption region is formed along the optical waveguide having a second optimized optical mode confinement characteristic independent of the first optimized optical mode confinement characteristic. The first optimized optical mode confinement characteristic is defined independently of the second optimized optical mode confinement characteristic.
