Abstract:
1. An optoelectronic device comprising: a waveguide structure including a plurality of optical modulator elements each having an optical property that is adjustable upon application of an electrical signal so as to modulate light guided in said waveguide structure; an electrical modulation signal line for supplying an electrical modulation signal to said plurality of optical modulator elements, said electrical modulation signal line having an input and having a plurality of outputs at different locations along said electrical modulation signal line such that said electrical modulation signal incurs different amounts of delay between said input and said plurality of outputs; and a plurality of amplifiers, each amplifier electrically coupled to one or more of said plurality of optical modulator elements between said one or more optical modulator elements and said electrical modulation signal line to apply said electrical modulation signal to said one or more optical modulator elements, said plurality of amplifiers being connected to said electrical modulation signal line at said plurality of outputs, wherein said waveguide structure comprises a path that undulates laterally such that the distance light propagates within the waveguide structure is substantially larger than the length of the waveguide structure.
