Abstract
This paper presents experimental data demonstrating a novel differential
quadrature phase-shift keying receiver based on optical frequency discriminator
demodulator with direct detection. The experimental results confirm theory,
showing a factor of 2$\times$ enhanced tolerance to chromatic dispersion compared with a conventional
delay-interferometer-based demodulator with balanced detection. The frequency
discriminator direct detection receiver also shows a significant improvement
in tolerance to Gordon–Mollenauer nonlinear phase noise.
