Zusammenfassung:	Structures including a photodetector and methods of fabricating such structures. A substrate, which is composed of a semiconductor material, includes a first trench, a second trench, and a pillar of the semiconductor material that is laterally positioned between the first trench and the second trench. A first portion of a dielectric layer is located in the first trench and a second portion of the dielectric layer is located in the second trench. A waveguide core is coupled to the pillar at a top surface of the substrate.
