Method And System For Waveguide Delay Based Equalization With Current And Optical Summing In Optical Communication

A system for communication, the system comprising:

• an optoelectronic receiver comprising a directional coupler, two or more photodiodes, and one or more current mirrors, the optoelectronic receiver being operable to:
• receive an input optical signal;
• split the input optical signal into first and second optical signals using the directional coupler;
• generate a first electrical signal from the first optical signal using a first photodiode;
• generate a second electrical signal from the second optical signal using a second photodiode;
• amplify the second electrical signal using the current mirror;
• and
• sum the first electrical signal with the amplified second electrical signal.
