STABLE OPERATION OF MICROWAVE PHOTONIC FILTERS CONSTRUCTED WITH TWO CASCADED HI-BI FIBERS

摘要

For the microwave photonic filters constructed with two cascaded Hi-Bi fibers, we demonstrate theoretically and experimentally a new technique that uses a dual- or tri-wavelength spacing-tunable laser source to greatly suppress the sensitivity of the filter response to environmental perturbations without the introduction of the phase-induced intensity noise.
