Coupling. Theory of Coupling Loss of an Ion Exchanged Multimode Channel Waveguide to Optical Fibers
-
J. Čtyroký
Summary
The potential applicability of multimode integrated optical branching waveguides and couplers is limited primarily by their coupling loss to optical fibers. To get a reasonably detailed theoretical insight, the fiber-to- fiber coupling loss of a section of a multimode channel waveguide fabricated, e.g., by ion exchange in a glass substrate is calculated using a ray-optic approximation. An approach of the length-averaged coupling loss results in a simple and efficient calculation procedure which enables one to optimize the parameters of a channel waveguide for minimum coupling loss. Coupling losses as low as 2 dB and 0.25 dB can be obtained for single channel and sandwich structures, respectively, coupled to standard graded-index fibers.
