Three-Dimensional Planar Integrated Optics: A Comparative View with Free-Space Optics

초록

This paper reports on the viability, effectiveness, versatility, and the utility of the concept of the planar integrated optical interconnection scheme with respect to the concept of the free-space interconnection scheme in realizing multiple integration of various micro/nano-photonic devices and components for applications in optical interconnection, optical circuits, optical switching, optical communication and information processing. A critical comparison between the planar integrated optics scheme and the free-space integrated scheme is given in terms of physics, engineering and technological concepts.
