| Abstract: | A novel variable optical attenuator based on SOI material was designed. The modulation area was formed of a special transverse PIN junction on a double-rib waveguide , which can enhance the overlap between the electric field and the optical field and accordingly increase the injection efficiency. The transmission characteristics of the new waveguide structure were analyzed using BPM method. The finite difference method was employed to analyze the 2D PIN junction injection characteristics. The result of the simulation shows that the attenuator with the new structure has a good performance. |
