Paper Abstract

The evanescent field coupling from a single-mode optical fiber, side polished close to the core, to a high index (> core index), multimode, planar waveguide overlay has been investigated as a means of realizing in-line components such as modulators, wavelength filters, and sensors without interruption of the fiber. Such structures offer considerable advantages in terms of fiber-to-device interfacing and ruggedization over other component technologies such as integrated, bulk, or micro optics. The results reported here confirm the technical feasibility of manufacturing rugged, low loss, all solid state devices of this nature, and the measured or projected performances are realistic in terms of application requirements.
