We present a detailed analysis of nonlinear signal impairments in the electro-optical (E/O) conversion of commercially available LEDs which are specifically designed for POF communication. Nonlinearities are assessed by measuring the generation of 2nd-order intermodulation products in the LED for different modulation frequencies, modulation indices, and bias points. It is shown that the nonlinear modulation behavior of the LEDs is strongly dependent on both modulation frequency and bias. The results further allow a derivation of a general system-theoretic model of the underlying physical processes, as well as conclusions on suitable equalization strategies. [ABSTRACT FROM AUTHOR] |
