Simulación del comportamiento del diodo led y de un diodo láser

Abstract

In this paper we simulate the sources most used optical fiber link and these are the led and láser diodes, for this is necessary to know the respective diodes equations describing their behavior, here is simulate diodes from of equations. In the analysis of láser diode simulate large-signal behavior and communications. In great sign we will focus on finding the threshold current láser diode, and also in finding operating points for use in the small-signal model. In the small-signal model we will focus on using these operating points found in the large-signal model and simulate the response of the diode in the frequency, also simulate its response to the pulse input and see the output photon density, density electrons and output power of diode láser. Diodes also look at the different power outputs when changing current values. It also simulate the behavior of the led, get the power to the led output. Also connect the diode with a block of optical fiber and observe its response
