Abstract

Motivation System impairments in optical links The most common deterministic impairment is intersymbol interference Two main types ISI ISI example: chromatic dispersion Overcoming deterministic system impairments Example: optical compensation of chromatic dispersion General optical equalization Common equalizer used in electronics (e.g., wireless communications) Very simple optical equalizer Example: try to make a 107-Gb/s transmitter Modulator bandwith limitation ISI in the modulation optoelectronics Solution: Two-tap OEQ Two-tap OEQ design Choice of tap time spacing Making the OEQ using integrated optics
