Improving the optical profile of electroabsorption modulator using single-sided large optical cavity structure
采用单边大光腔结构改善电吸收调制器的光场分布

An electroabsorption modulator with large optical cavity was designed and fabricated successfully. Both the simulated and experimental results show that, the larger optical cavity structure introduced could obviously improve the optical profile of EA modulator, the traditional elliptical near-field spot becomes more rounded, so it will match better with the optical fiber and is beneficial for raising the coupling efficiency.
