Title: High density optical waveguide using hybrid spiral pattern

Abstract

A hybrid spiral waveguide geometry is proposed that exhibits essentially zero curvature (i.e., infinite bend radius) at the center of the spiral (similar to a Fermat spiral), with the curvature then increasing in value as the spiral moves outward. Advantageously, as the spiral moves away from the center, the spacing between adjacent waveguides quickly approaches a constant value (similar to an Archimedean spiral). This hybrid spiral structure has been found to allow for a high density waveguide to be created with lower loss and requiring a smaller size than many conventional spiral configurations and finds use in optical delay lines, amplifiers and arrayed waveguide gratings.
