Abstract
The present disclosure provides an optical modulating structure. The optical modulating structure includes a lower member extending along an insulating layer, a first protrusion over the lower member, and a second protrusion over the lower member and separated from the first protrusion. A first mask layer is formed over the optical modulating structure, wherein the first mask layer covers the second protrusion and a first portion of the lower member between the first protrusion and the second protrusion. A first doping region is formed in an exposed portion of the lower member and at least a portion of an exposed sidewall of the first protrusion. A dielectric layer is formed between the first protrusion and the second protrusion. A method for manufacturing the optical modulating structure is also provided.
