Different requirements of guidance and control of UAV were already identified; however, the communication facilities between mobile platforms and air-to-ground links are restricted to low bit rate radio based technology. In the near term data rates in the area of 100 Mbit/s to 1 Gbit/s will be needed to handle multiple sensor information in real-time and in parallel. Thus, UAV equipped with free space optics (FSO) will emerge as a challenging new needs for large data transfer in real time.

This structure shows unresolved heavy hole and light hole transitions. So, the device operation mode (amplification or switching) is independent of input light polarization. A rigorous numerical analysis for dynamic response and relative intensity noise of the device is presented. The model is based on device rate equations, for which we require to calculate the MQW-LD gain and phototransistor electroabsorption coefficient. The Hamiltonian of strained QW structure is numerically solved by transfer matrix method taking into account the band mixing between heavy hole and light hole. In order to calculate the electroabsorption coefficient, the exciton equation is solved numerically in momentum space using Gaussian quadrature method.
