Abstract

In this paper, we unveil and discuss a theoretical misconception in a classical formalism of Gaussian pulse envelope propagation. With simple analytical arguments, we explain the mistake and develop a universal result, valid for short and ultra‐short optical pulses of arbitrary shape. This general result sheds light on the mathematical separation of a pulse into its envelope (energy) and its coherent characteristics (frequency chirp). With it, a theoretical ground is provided for the use of blind numerical computations to calculate complex photodetected pulse shapes. © 2003 Wiley Periodicals, Inc.
