Gaussian shaped pulse
WebAssume a Gaussian pulse shape for simplicity, the electric field of an optical pulse train in the time domain can be expressed as (5.4.1) E t = A 0 ∑ m exp − t − mτ 2 σ 2 cos 2 πft + φ where A 0 is the pulse amplitude, f and φ are frequency and phase of the optical carrier. WebMuch insight on how dispersion affects a pulse can be gained using the simple approximation of phase in (2) and a gaussian pulse shape. The gaussian pulse can be described by, (3) where τ is a measure of the pulse width. The spectrum of this gaussian pulse, denoted ē in (ω), also has a gaussian profile, and can be written. (4)
