TLDR
The far-field patterns of the output beam from the second prism coupler were consistent with the calculated transverse field distributions using the effective index-of-refraction method.Abstract:
Experimental investigations of the partially metal-clad optical guide were performed. The optical guide consisted of a silicon substrate, an SiO2 low index dielectric layer, an Al2O3 high index dielectric layer, and a partial cladding layer of Al. The far-field patterns of the output beam from the second prism coupler were consistent with the calculated transverse field distributions using the effective index-of-refraction method. The experimental results on the coupling angles, confinement at the curved section, and attenuation constants are also reported.read more

Guidance and Leakage Properties of a Class of Open Dielectric Waveguides: Part II--New Physical Effects
TL;DR: In this article, a class of open dielectric waveguides is discussed which is of direct importance to the areas of integrated optics and millimeter-wave integrated circuits, and an accurate analysis of the properties of these waveguiders reveals that interesting new physical phenomena, such as leakage and sharp cancellation or resonance effects, may occur under appropriate circumstances.

Characteristics of Optical Guided Modes in Lossy Waveguides
TL;DR: A generalized procedure is presented that permits an accurate description of metal boundaries at optical frequencies and it is found that, with increasing buffer thickness, TM(N) modes undergo a continuous transformation to becomeTM(N+1).
