Summary:
Higher than 55GHz electro-optical (EO) response was measured in electroabsorption modulator (EAM) fabricated by using the two-step-undercut- etching-active-region-waveguide (TSUEARM) method, It is shown that the high-speed EO performance can be obtained by simultaneously reducing cladding resistance, parasitic capacitance and the electrical insertion loss.
