  • Abstract
    The intrinsic square-law non-linear function of the photodiode, between the optical field amplitude and the generated current, can be partially compensated by means of a simple non-linear electrical circuit performing a square-root function after the photodiode. Practical implementation has been carried out, and the experimental and simulation results with MLSE, FIR and RoF demonstrate the performance enhancement.
