“…To avoid the power fading effect, an SSB modulator should be employed.

“…Due to the merits of the single-bandpass response, the invariant passband shape, and the cost-effective setup, many single-bandpass MPFs based on the IBOS have been proposed. These MPFs can be classified in terms of their employed modulators, such as the Mach-Zehnder modulator (MZM) [11], the single-sideband (SSB) modulator [12], the phase modulator [13], the polarization modulator [14], and the dual-input modulator [15]. Moreover, the IBOS-based single-bandpass MPF has been widely used in radio-over-fiber (RoF) communication systems [16], [17], optoelectronic oscillators (OEOs) [18], [19] and microwave frequency multiplication [20].…”

A comprehensive investigation of the signal-to-noise ratio (SNR) of the microwave photonic filter (MPF) with an interferometric structure based on an incoherent broadband optical source (IBOS) is presented from the time and frequency domains, respectively. The interferometric structure and the IBOS in the MPF result in a beneficial single-bandpass radiofrequency (RF) response. However, the IBOS adds a relatively large noise to the filtered RF signal. Therefore, the analysis of the SNR is of great importance for the design of this kind of MPFs. Theoretical analysis shows that the SNR is a function of the center frequency of the passband, the modulation index, the chromatic dispersion, and the shape of the IBOS. An experiment is performed to verify the theory, and experimental results agree well with the theoretical calculation.

“…In [47], single passband microwave photonic filter structure was achieved by controlling the dispersion-induced RF fading and the carrier suppression effect, so that the notch frequencies fall on the periodic spectral resonances. The development in single passband spectrum-sliced microwave photonic filter are either based on the Fourier-transform of optical spectrum into RF domain [11,[48][49][50], or the shifted dispersion-induced RF fading using a dual-input Mach-Zehnder interferometer configuration [9,[51][52][53]. Optical filtering techniques have also been extensively applied to apodize broadband optical source with a Gaussian windowing function, hence greatly increasing the filter sidelobe suppression ratio [9,[51][52][53].…”

Microwave photonics, based on optical filtering techniques, are attractive for wideband signal processing and high-performance sensing applications, since it brings significant benefits to the fields by overcoming inherent limitations in electronic approaches and by providing immunity to electromagnetic interference. Recent developments in optical filtering based microwave photonics techniques are presented in this paper. We present single sideband modulation schemes to eliminate dispersion induced power fading in microwave optical links and to provide high-resolution spectral characterization functions, single passband microwave photonic filters to address the challenges of eliminating the spectral periodicity in microwave photonic signal processors, and review the approaches for high-performance sensing through implementing microwave photonics filters or optoelectronic oscillators to enhance measurement resolution.

A tunable and flat single-notch microwave photonic filter (SNMPF) with a multi-wavelength optical source is proposed and demonstrated. In the experiment, the multi-wavelength optical source is based on a tunable laser and a broadband optical source, which has the ability to achieve separate control of the first tap and secondary taps. Through a large number of tap amplitude tests and simulations, the filter can achieve a flat-passband; the passband ripples are smaller than 0.65 dB. The notch depth of the SNMPF is tuned by changing the amplitude of the first tap. The frequency of the SNMPF is continuously tuned by controlling the Fourierdomain optical processor to induce an additional phase, and the 3 dB bandwidth of the filter is tuned by controlling the waveshaper to adjust the number of taps. For simulation results, the depth of the SNMPF is tuned from −43 dB to −14.73 dB, the center frequency is tuned continuously from 0 GHz-74.488 GHz, the bandwidth with 10-taps is 3.54 GHz and the SNMPF has a flat-passband.
