Optoelectronics systems simulations, Sep 2019 - Sep 2020

This repository contains various files and reports regarding optoelectronics systems simulations. Those works were implemented as part of my own laboratory studies at Keio University (Japan). Each file contains MATLAB simulations and a complete reports of the case study.

More precisely :

• Report 1 deals with laser diode and optical transistors
• Report 2 deals with optical diffraction light propagation
• Report 3 optical fibers simulations and effects in networks

Results

Laser diode and optical transistors

Fig.1 - Power vs current curves for various design parameters

Optical diffraction light propagation

Results example for nontrivial double-slit antenna type

Fig.2 - Illuminated double slit aperture acting as an antenna, x and y indexes are space samplings

Fig.3 - Illuminated double slit aperture results using fft

Fibers simulations and effects in networks

Several kind of pulses were analyzed along wth their 2nd and 3rd order dispersion in networks

Fig.4 - Second order dispersion of a gaussian pulse in network solving both using analytic formula and numerical method

Fig.5 - Pseudo-random bit sequence third order dispersion in networks, pulse of 1ps
