Abstract: Structures for managing light polarization on a photonics chip and methods of forming a structure for managing light polarization on a photonics chip. A single-mode waveguiding structure is formed that includes a first waveguide core region and a second waveguide core region positioned above the first waveguide core region. The second waveguide core region includes a first section, a second section connected to the first section, and a third section connected to the second section. The second section has a first width at an intersection with the first section and a second width at an intersection with the third section. The second width is greater than the first width. The first and second waveguide core regions contain materials of different composition.

Abstract: Structures for polarization filtering and methods of forming a structure for polarization filtering. A waveguiding structure has a first waveguide core region including a first plurality of bends, a second waveguide core region including a second plurality of bends laterally spaced from the first plurality of bends by a gap, and a third waveguide core region including a third plurality of bends positioned beneath the gap. The first waveguide core region and the second waveguide core region contain a first material. The third waveguide core region contains a second material that differs in composition from the first material.

CPC classification number: G02B6/1228 , G02B6/13
Abstract: Structures including an edge coupler and methods of fabricating a structure including an edge coupler. The structure includes a waveguide core region on a first dielectric layer, and a second dielectric layer on the waveguide core region and the first dielectric layer. The waveguide core region has a tapered section with an end surface that terminates adjacent to an edge of the first dielectric layer. The second dielectric layer includes a first trench and a second trench that are each positioned adjacent to the tapered section of the waveguide core region.
