Abstract
An electro-optic modulator may include a radio frequency (RF) modulation region including a first optical waveguide, a second optical waveguide, a first set of electrode segments, a second set of electrode segments, and a conductive strap. The first optical waveguide may propagate a first optical signal. The second optical waveguide may propagate a second optical signal. The first set of electrode segments may apply a first RF signal to the first optical waveguide. The second set of electrode segments may apply a second RF signal to the second optical waveguide. The conductive strap may enable photocurrent generated in the first optical waveguide and the second optical waveguide and flowing through a doped layer below the first optical waveguide and the second optical waveguide to be extracted from the electro-optic modulator. The conductive strap may be ohmically contacted with the doped layer.
