Abstract
An integrated chip including a base dielectric layer and a multi-tiered semiconductor waveguide layer over the base dielectric layer. The multi-tiered semiconductor waveguide layer has a first waveguide tier having a first width at a first height over the base dielectric layer. The multi-tiered semiconductor waveguide layer has a second waveguide tier having a second width, greater than the first width, at a second height, less than the first height, over the base dielectric layer. A cladding layer is over the multi-tiered semiconductor waveguide layer. A multi-tiered conductive heater layer is over the cladding layer. The multi-tiered conductive heater layer has a first heater tier over the first waveguide tier. The multi-tiered conductive heater layer has a pair of second heater tiers at the first height, over the second waveguide tier, and on opposite sides of the first waveguide tier.
