Other methods include optical phase lock loops [10], nonlinear effect of stimulated Brillouin scattering (SBS) within the Brillouin frequency [11][12][13][14] and filter-less frequency 12-tupling using DP-MZM is also a quite famous method, among the above techniques due to low cost, less complexity and excellent frequency tunability [15].…”

We propose experimentally a technique to generate a low noise frequency octupled microwave signal. We demonstrate that by carefully arranging the phase of 90° between two MZMs (out of three), a low noise photonically assisted octupled microwave signal can be generated. A 25.6 GHz optical microwave signal is achieved with 3.2 GHz of local RF oscillator signal. Moreover, the intensity expressions at the output of photodiode are derived for both with and without dispersion terms. Finally, we advocate the impact of the electrical spurious suppression ratio on the extinction ratio of the modulators. Our experimental and simulation results agree well with the theoretical analysis.

“…However, it has been theoretically and experimentally proved that dual mode modulation also caused CSE [5,7]. Recently, we have demonstrated that data upconversion with single mode modulation is more promising compared with dual mode modulation for overcoming the CSE [8]. Therefore, single mode and SSB modulation is an effective way to eliminate the CSE in RoF systems [9].…”

“…In RoF systems, it is of great interest that the information can be downconverted directly in the optical domain from a highfrequency band to a low intermediate frequency (IF) band. Previously, various photonic frequency downconverters were proposed, including the schemes based on cascaded Mach-Zehnder modulators (MZMs) [2], parallel electrooptic modulators (EOMs), and a balanced photodetector (BPD) [3], an injection-locked distributed feedback laser [4,5], a semiconductor optical amplifier (SOA) [6][7][8][9][10][11][12], and a parametric optical loop mirror [13]. However, most of these schemes are highly polarization dependent, so adaptive polarization control is required at the center office to achieve the highest conversion efficiency, which is complex, costly, and bulky.…”

A polarization-insensitive photonic microwave downconverter is proposed and demonstrated, which is comprised of a polarization beam splitter, two Mach-Zehnder modulators (MZMs), and a balanced photodetector. By biasing the MZMs at the quadrature bias points with opposing modulation slopes, the performance of the proposed photonic microwave downconverter is almost independent of the polarization state of the optical microwave signal for down conversion. An experiment is performed, which shows that the polarization dependent loss of the proposed downconverter is less than 0.06 dB. The downconverter is also evaluated in a radio-over-fiber link. A 20 GHz RF signal with 20 MBaud 16 quadrature amplitude modulation baseband data is successfully downconverted to a 1 GHz IF signal. When the polarization state of the input optical microwave signal is adjusted, the variation of the error vector magnitude of the downconverted signal is less than 0.4%.
