abstract

  • An analysis of a GaAs/AlGaAs electrooptic intensity modulator is carried out by using the finite element method. The microwave properties, e.g., the effective index, the characteristic impedance, and the frequency dependent attenuations are calculated using quasi-TEM analysis. The 3-dB optical bandwidth is estimated and it is shown that microwave losses in the dielectric material is an important factor in determining the bandwidth of the modulator. Next, to carry out the optical analysis, electrooptic effect is considered and optical mode fields and half-wavelength voltage length product is calculated using a vectorial finite element method. The results are compared with the published results and very good agreements have been found. ©2010 IEEE.
