Abstract :
Numerical results for the second- and third-order dispersion in PW prism-sequence (double prism-pair) with arbitrary apex-angle by ray-tracing method are presented. The influence of the prism separation distance and apex-angle on second- and third-order dispersion is discussed. In certain conditions, the PW prism-sequence with small apex-angle (20°) is a better choice to reduce third-order dispersion than single prism-pair without requiring excessive length. As a less dispersion material, quartz is suitable to be used with the smallest possible value of third-order dispersion. This result could be the basis of dispersion compensation and pulse compression.
