“…Notwithstanding the laser rate Equations (2) are one of the simplest possible mathematical descriptions of single-mode semiconductor laser diodes, important properties of DMLs concerning the transmission system performance assessment, such as power overshoot, relaxation oscillations, damping, and wavelength chirp, can be described satisfactorily (see e.g. [12], pp. 614-625, [17], Chapter 2).…”

“…Directly modulated laser diodes (LDs) are widely used in optical fiber communications, particularly in access networks [1][2][3][4][5][6]. In order to meet the desired performance specification on RF parameters, particularly the extinction ratio (ER) and the average optical power, optimum bias and modulation currents should be found for a specific LD.…”

“…A informação é modulada sobre a corrente de controle do laser, resultando num formato de modulação em intensidade binária (OOK -On-off keying) [60,61]. Atualmente, os lasers modulados diretamente são largamente empregados na modulação de taxas de 2,5 Gb/s, com alguma disponibilidade em 10 Gb/s.…”

“…A principal desvantagem de lasers modulados diretamente para transmissão de altas taxas de bits para aplicações além de acesso a curtas distâncias é seu chirp, isto é, modulação de fase residual acompanhando a modulação em intensidade desejada. O chirp do laser alarga o espectro óptico, o qual impede o empacotamento de canais WDM denso e pode conduzir a distorções do sinal intensificadas causadas pela interação com a dispersão cromática da fibra [2,60,61]. …”
