Abstract
A semiconductor structure includes a waveguide and an optical attenuator. The waveguide is disposed over an insulating layer and configured to guide light. The optical attenuator is connected to the waveguide. The optical attenuator has a first surface and a second surface opposite the first surface, and a cross-sectional width of the optical attenuator decreases from the first surface to the second surface.
