N2 - The 4-quadrant detector is the optical sensor used in laser applications alignment, tracking and optical communications; have been modeling, performance evaluation, and measurement and modeled using its differential equations then implemented and solved using ORCAD-spice. The model results were compared with the experimental measurements using a proposed setup and it is used to investigate the effect of the photodiode donor concentrations, and intrinsic region concentrations. The simulation results showed that the donor concentrations should be kept as small as possible in order to improve the photodiode performance, and as the intrinsic region concentration increases the photocurrent increases and the junction capacitance decreases with a small increase in the dark current. The difference measurement values in the four photodiode of the quadrant detector are due to the manufacturing division of the quadrant detector to four photodiode are not the same.
