Abstract
A device, such as a silicon modulator, in accordance with the present disclosure employs PN diodes without sacrificing the modulation depth, while achieving lower loss and better impedance matching to 50-Ohm drivers. In one embodiment, the device includes an input waveguide, an input optical splitter coupled to the input waveguide, first and second optical phase shifters coupled to the input optical splitter, an output optical splitter coupled to the first and second phase shifters, and an output waveguide coupled to the output optical splitter. The phase shifters are designed with variant capacitance per unit length.
