Abstract

See full text

A method of modulating an optical input with a radio frequency (RF) signal, an interdigitated modulator, and an electro-optical modulator including the interdigitated modulator are described. The method includes splitting the optical input to a first optical input and a second optical input, traversing a first region and a second region, respectively, with the first optical input and the second optical input, and modulating the first optical input with the RF signal in the first region. The method also includes controlling propagation speed of the RF signal in the first region, controlling RF line impedance in the first region, and controlling an optical loss of the first optical input in the first region.
