  • Low Non-Linear Loss Silicon Waveguides with Sweep-Out Diodes
    Publication number: 20230393424
    Abstract: An optical waveguide includes a core region extending substantially along a lengthwise centerline of the optical waveguide, a first cladding region formed along a first side of the core region, and a second cladding region formed along a second side of the core region. The optical waveguide includes a first diode segment and a second diode segment that each include respective portions of the core region, the first cladding region, and the second cladding region. The second diode segment is contiguous with the first diode segment. The first diode segment forms a first diode across the optical waveguide such that a first intrinsic electric field extends across the first diode segment in a first direction, and the second diode segment forms a second diode across the optical waveguide such that a second intrinsic electric field extends across the second diode segment in a second direction opposite the first direction.
