Abstract
The intensity spectrum of modulated noisy light on optical microwave signal processing and on conversion of FM noise to intensity noise in optical links is investigated theoretically and experimentally with a good agreement. We have applied a model that uses a 1550 nm distributed feedback (DFB) laser and an unbalanced Mach-Zehnder interferometer (UMZI) considering the external phase modulator. Numerical calculations show the influence of the phase modulation index, modulation frequency, and interferometric delay in the phase-to-intensity noise conversion by lowest-order group-velocity dispersion in optical fiber. The results can be employed to estimate the influence of the chromatic dispersion in phase-to-intensity noise conversion, which use either self-delayed interferences or interferometers.
