The advent of integrated optics and the availability of low-loss fibers prompted a renewed urgency in the understanding of the guiding properties of optical fibers. The present presentation is concerned with the propagation characteristics of waves along a non-circular fiber. Three analytical methods in treating this problem will be discussed one on the exact solution of modes on elliptical fiber, the other on the numerical solution of modes on rectangular fiber and the third on the approximate solution of modes on complex structure of rectangular fibers. Significant differences between guided modes along a circular fiber and those along a flattened fiber are discussed in detail. Theoretical results on dominant modes have also been verified by experiments at microwave frequencies. Author
