发明名称 VARIABLE OPTICAL ATTENUATOR USING WAVEGUIDE MODIFICATION
摘要 A variable optical attenuator is disclosed having a waveguide modification. Light coupling from an input waveguide to an output waveguide is electrically controllable through an electrically variable refractive index region, wherein attenuation of the device is dependent upon the applied voltage to the electrically variable refractive index regio n.
