Abstract
A novel 1.55-?m spot-size converter integrated electroabsorption modulator was designed with conventional photolithography and chemical wet etching process. A ridge double-core structure was employed for the modulator, and a buried ridge double-core structure was incorporated for the spot-size converter. The passive waveguide was optically combined with a laterally tapered active waveguide to control the mode size. The figure of merit is 4.1667 dB/V(/100 ?m) and the beam divergence angles in the horizontal and vertical directions were as small as 11.2 deg. and 13.0 deg., respectively.
