“…We did our measurement at an electrical power of 7 dBm, which is applicable to other driving levels since our method does not assume any small-signal operation [10,11]. Moreover, the method can be extended to other wavelengths and other dispersive fibers as long as the operation meets the dispersion requirement.…”

We propose a new method for characterizing optical phase modulators based on phase modulation-to-intensity modulation (PM-to-IM) conversion in dispersive fibers. The fiber dispersion spectrally alters the relative phasing of the phase-modulated signal and leads to the PM-to-IM conversion, which is extended to measure the modulation efficiency of optical phase modulators. In the demonstration, the frequency-dependent modulation index and half-wave voltage are experimentally measured for a commercial phase modulator. Compared with conventional methods, the proposed method works without the restriction of small-signal operations, and allows swept-frequency measurement with high resolution and accuracy by using a vector network analyzer. electro-optic modulators, microwave photonics, optical fiber dispersion, phase modulation Citation:Zhang S J, Lu R G, Chen D J, et al.

“…Moreover, in comparison with the direct transmission of microwave carriers over a fiber link, which suffers carrier suppression at specific fiber lengths due to chromatic dispersion, OFM presents a higher dispersion tolerance, thanks to the FM to IM conversion performed with the MZI, which enhances the generation of higher order harmonics through a dispersive element [11]. This is especially interesting in multimode fiber (MMF) links, where the transmission bandwidth for direct modulated microwave carriers is dramatically limited by modal dispersion.…”

Abstract-Employing optical frequency multiplication, we demonstrate experimentally the simultaneous delivery of different 64QAM radio signals at 5.8 and 17.7 GHz after 4.4 km of multimode fiber in a single radio-over-fiber link. We also propose a flexible mechanism for the dynamic radio link adaptation, and the simultaneous transmission of an in-band control channel with the wireless data channels for power control purposes at the antenna site is demonstrated experimentally.Index Terms-Broadband wireless access, optical fiber communications, radio-over-fiber systems.
