Photonic links have been proposed to transport radio frequency (RF) signals over optical fiber communication systems. External optical modulation is commonly used in high performance RF photonic links. The practical use of optical fiber communication systems to transport RF signals is still limited due to high RF signal loss. In order to reduce the RF signal loss, highly efficient modulators are needed. For many applications, modulators with broad bandwidths are required. However, there are applications that require only a narrow bandwidth. For these narrow band applications, the modulation efficiency can be improved through the resonant enhancement technique at the expense of reduced transmission bandwidth. Therefore we have been investigated to get the best performance of the transmission bit rate capacity and product of different semiconductor materials based electrooptic (EO) modulators over wide range of the affecting parameters
