HIGH-INDEX CONTRAST DISTRIBUTED BRAGG REFLECTOR

摘要

A distributed Bragg reflector has a sectioned waveguide with a high index of refraction. The waveguide is disposed within a medium having a relatively low index of refraction. Each of the sections of the waveguide are coupled with a thin waveguide having a high index of refraction. In one embodiment, AD wire and waveguide sections are formed of the same high index material.
