Abstract

The incoupling and outcoupling angles of a thin film waveguide were determined using the conventional prism coupling configuration. The consistent intermodal spacing observed between incoupling and outcoupling angles indicated that these angles contained equivalent information on the waveguide structure. However, a geometry mismatch between the rotation goniometer and the triangular coupling prisms produced a systematic error in the determination of the outcoupling angles that increased with decreasing mode number.
