Chirped gaussian pulse
WebNov 1, 2013 · For linearly chirped Gaussian pulses from gain-switched semiconductor lasers, the pulse shape in the time domain is [11] (1) E ( t) = exp − ( 1 + i C) 2 t 2 T 0 2 where E ( t) is the normalized electrical field, C is a chirp parameter, and it is common to refer to the chirp as being positive or negative, depending on whether C is positive or … A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum). This signal type is biologically inspired and occurs as a ph…
