Abstract

The mode-field half widths of two kinds of single-mode waveguides are investigated. Based on the maximal matching efficiency method, the relationship between the mode-field half width and normalized frequency is analyzed. Furthermore, two equations of mode-field half widths as a function of normalized frequency are proposed through mathematical modeling and the curve fitting method. Numerical calculations indicate that they are accurate within a parameter range.
