Abstract
This article presents the implementation of an interactive software that integrates various functional blocks of an optical receiver of intensity modulation and direct detection (IM-DD), with OOK (on-off keying) digital modulation and NRZ (non-return-to-zero) pulse format. The software allows for the isolated simulation of each block, as well as the complete simulation of the whole system. We underline the following results presented by the simulator: theeye diagram, the probability density functions of the samples, Bode diagram, bandwidth, transimpedance gain, signal-to-noise ratio, power of the different noise sources and the bit error probability of the simulated system.
