Abstract:

The design and simulation of a Micro Electro Mechanical Systems (MEMS)-based Optical Signal Processing (OSP) beam former for cellular network base stations are reported in this paper. The modulated optical signal destined for a mobile terminal is split into eight equal-intensity signals. Each signal is weighted by controlling the phase and amplitude using a pair of micromirrors driven by electrostatic comb drive actuators. The processed optical signal is heterodyned with a phase-locked local optical signal. The resulting weighted microwave signal is then fed to the corresponding element of the 1 × 8 antenna array. The radiation patterns of the proposed multibeam-forming network are simulated using MATLAB and SIMULINK.
