Background:

Second-harmonic generation (SHG) is a key nonlinear optical process.
SHG typically requires specific phase-matching conditions.
Previous SHG studies often focused on anomalous dispersion regimes.

Purpose of the Study:

To investigate a different type of SHG in nonlinear optical fibers.

To determine if phase-matching for SHG can be achieved in a normal dispersion regime.

Main Methods:

Utilizing a multiscale method to derive equations.
Deriving nonlinearly coupled envelope equations for SHG.
Obtaining explicit analytical solutions for the derived equations.
