Gaussian pulse wave
WebThe chirped Gaussian input pulses are the pulses which are usually produced from directly modulated semiconductor lasers. As in SOA gain saturation—Gaussian pulses, we will consider the pulses with a pulse width much shorter than the carrier lifetime. The carrier wavelength of the Gaussian pulse is 1.55 mm. WebJul 22, 2014 · An isolated rectangular pulse of unit amplitude and width w (the factor T in equations above ) can be generated easily with the help of in-built function – rectpuls(t,w) command in Matlab. As an example, a …
