A resonant optical modulator includes an electro-optical substrate, an optic al waveguide formed in the substrate and having a variable index of refraction, and an active modulator electrode formed on the substrate in relation to the waveguide to effect electro-optical variation of the index of refraction upon application to the electrode of a modulating signal. An interface port formed on the substrate provides the modulating signal to the electrode from a signal source and has an impedance. An electrical structure, formed on the substrate and coupled to the interfac e port and the electrode, makes an impedance of the optical modulator substantially equ al to the impedance of the signal source. The electrical structure includes a delay li ne and a stub formed on the substrate. |
