Abstract
In some implementations, an electro-optic modulator may include a waveguide to propagate an optical signal in a direction of propagation. The electro-optic modulator may include a signal electrode, associated with the waveguides, to modulate the optical signal. The signal electrode may include a base structure. The signal electrode may include a loading line structure comprising one or more segments, where a segment, of the one or more segments, connects to the base structure via a plurality of electrically-conductive bridges.
