In this two-part study, the conclusions drawn from optimization of interferometer incoherent detection carried out by examining the effect of pre-emphasis within the electrical signal-driving path are examined first. This is an expansion upon a widespread industry standard as realized by the Oclaro group. System performance in tight optical filtering conditions can be improved with concurrent adjustments to the level of pre- emphasis and breadth of the delay-line interferometer free-spectral range. In the second study, we implement a dual-polarization quadrature phase-shift keyed modulation format with a digital signal processing block based upon the constant modulus algorithm realized via a feed-forward equalizer with and without the moving average method. Ultimately, the purpose of both studies is to study the efficacy of new modulation formats to enhance gains in spectral efficiency and improve robustness against chromatic dispersion within the optical fiber.
