Caracterização de gain chips tipo MQW para aplicação em lasers de cavidade externa.

Abstract

Lasers are optoelectronic devices that convert electric energy into optical energy, working as sources of signals for optical communication systems. Gain chips are active components of lasers that would emit photons in certain range os frequencies. In special, Multi Quantum Well gain chips provide good characteristics such as high output power and can operate in high temperatures. In this work will be presented simulations of Multi Quantum Well lasers, starting with modal simulations, next performing quantum system wavefunction calculation and finishing with cavity simulations. The simulations are of gain chips of Idea! Electronic Systems company, from which measured data will be compared with the results of the performed simulations.
