Abstract
An E/O phase modulator may include a waveguide having an insulating substrate, a single-crystal silicon strip and a polysilicon strip of a same thickness and doped with opposite conductivity types above the insulating substrate, and an insulating interface layer between the single-crystal silicon strip and polysilicon strip. Each of the single-crystal silicon strip and polysilicon strip may be laterally continued by a respective extension, and a respective electrical contact coupled to each extension.
