Abstract

This paper presents the modeling, design, experimental results and applications of integrated optical elliptic couplers. An approximate analytical model is presented and the design procedure is described. Some elliptic focusing and collimating structures have been experimentally tested and the results are in good correspondence with the design. The couplers have low losses, are polarization and lateral index contrast insensitive, compact, and easy to design and fabricate. The potential and limitations of the device are evaluated. Some applications of the elliptic couplers are also presented
