System for Confined Optical Power Delivery and Enhanced Optical Transmission Efficiency.

摘要

A system for confined optical power delivery and enhanced optical transmission efficiency includes a waveguide defining an aperture, a focusing element, and a coupling layer positioned between the waveguide and the focusing element. The waveguide may be, for example, in the form of a ridge waveguide. The focusing element is formed of a material having a refractive index that is greater than a refractive index of the coupling layer. The focusing element may be, for example, a solid immersion lens or a solid immersion mirror.
