“…Using the commercial photoelectric devices without any electrical amplifier, the conversion gain of this mixer is -14.6 dB and has achieve the same level relative to other high efficient photonic mixers recently proposed. The conversion gain can be further improved by increasing the optical power and using a PD with larger power handling ability, or using impedance matching techniques for the detected mixing signals [34].…”

The conversion gain of a photonic microwave mixer is often limited by the large carrier of the modulated optical signal, and may be further deteriorated by the chromatic dispersion-induced power fading after transmission over fiber. To solve this problem, an efficient photonic microwave mixer based on a dual-electrode Mach-Zehnder modulator (DEMZM) is proposed in this paper. The carrier of the modulated optical signal is suppressed by bidirectional use of the modulator in a Sagnac loop, and a 21.9-dB improvement of the conversion gain is achieved in the experiment. In addition, the frequency response of the mixer after transmission over fiber can be tuned by simply adjusting the direct current (DC) bias of the modulator. This feature is applied to compensate the dispersion-induced power fading of the mixing product. In the proof of concept experiment, a vector signal centered at 2.4 GHz is up-converted to 16 GHz and transmitted over 25-km single mode fiber (SMF). After power compensation, the constellation diagram, error vector magnitude (EVM) and receiver sensitivity are significantly improved, and are almost as good as that without fiber transmission.Index Terms-Chromatic dispersion, microwave photonics, microwave mixer, photonic frequency conversion, power fading.

“…For the RF signat the close to carrier phase noise spectrum corresponds to a phase stability around 80 dB in 1 MHz bandwidth. A pulse-to-pulse stability measurement has confirmed this performance, and shown an equivalent contribution of phase and amplitude noise on the stability [9]. The reduction of losses provided by the reactive matching network allows reaching the close to carrier phase noise floor (-155 dBc/Hz to -140 dBc/Hz) and phase stability (80dB in 1MHz) required for LO and RF pulsed signals.…”
