US Patent 10054806 Segmented electro-absorption modulation

Systems and methods therefor relating generally to electro-absorption modulation are disclosed. In a system thereof, a waveguide is for propagating an optical signal. A segmented electro-absorption modulator (“SEAM”) includes: a segmented anode having at least two anode segments spaced apart from one another alongside a first side of the waveguide; and a segmented cathode having at least two cathode segments spaced apart from one another alongside a second side of the waveguide corresponding to the at least two anode segments.
