| Abstract: | In this article, rectangle, trapezoidal and T type microstrip lines embedded into up cladding of the waveguide are designed.
By the analysis of the finite element method (FEM), this embedded microstrip line has perfect velocity matching between the
electric signal and lightwave carrier and at the same time, conductor loss of the trapezoidal and T type microstrip lines
also reduce. Thus the modulator’s bandwidth increases greatly. Calculations show that, comparing with one of non-embedded
rectangle microstrip line which is the most familiar configuration of polymer modulator, the optical 3-dB bandwidths of embedded
trapezoidal and T type microstrip increase 264% and 339% respectively under the condition of impedance matching. |
