“…Bulky conventional lithium niobate (LN) modulators offer a high SFDR of around 110-120 dB/Hz 2/3 , compared to etched LN waveguide modulators with an SFDR of around 97.2 dB/Hz 2/3 [14]. Suppressing IMDs in optical modulators is challenging, and various linearization techniques [15][16][17] are utilized to improve SFDR. However, these are out of the scope of this article.…”

Electro-optic modulators (EOMs) are crucial devices for modern communication enabling high bandwidth optical communication links. Traveling wave electrodes are used to obtain high-speed modulation in these EOMs. We present the electrode design and analysis along with the study of effects of changing orientation on device performance for a thin-film lithium niobate tunable Mach–Zehnder interferometer (MZI) that offers sub-THz bandwidth operations. High velocity and impedance matching with low RF attenuation, high third-order SFDR (∼121 dB/Hz2/3) and a low half-wave voltage length product (1.74 V.cm) have been achieved for a bandwidth of 136 GHz. High-speed digital modulation using multi-level signal formats (PAM-2, QAM-4 and QAM-16) with low BER for 400 Gbps data has been demonstrated to assess the digital performance of the device.

In this paper a novel Microwave Photonics Analog Link (MPAL) system configuration based on two Dual-drive Dual-parallel Mach–Zehnder modulators (D-DPMZMs) and two Balanced Photo-Detectors (BPDs) is developed and system performance parameters are optimised for Radio over Fibre (RoF) high-speed transmissions. The Intermodulation Distortions (IMDs), as well as the harmonic distortions have been eliminated. The proposed linearization of RF signal configuration is double side banded in both D-DPMZM. A detailed mathematical system modelling is developed for the proposed RoF system configuration, benchmarked against newly generated system simulations, and implemented utilising particular device characteristics derived from experimental work. The proposed Microwave Photonic Link (MPL) system uses fewer RF shifters and is easier to implement in actual applications since all of the system's commercially available off-the-shelf components have already been experimentally demonstrated. The RF linearization for this configuration has been tested by introducing an additional RF signal, as well as phase and intensity errors in MZ branches. The proposed novel linearized MPAL with high spurious free dynamic range would have a great impact on future aerospace, radar, defense and satellite-to-ground downlink communication systems applications.

“…Experimental results, simultaneously, demonstrate a significant increase of Second-order Spurious free Dynamic Range (SFDR2) and Third-order Spurious-free Dynamic Range (SFDR3) by 19.5dB and 3.1dB, respectively. The performance analysis of microwave photonic frequency conversion has been recorded to use a double-sideband suppressed-carrier and balance based on DPMZM [14]. The double-sideband technique has been used to suppress high harmonics and high Intermodulation's, as well as achieve frequency conversion signals.…”

A full mathematical model has been developed and simulations have been implemented for the proposed configuration. The RF linearization for this configuration has been tested by introducing an additional RF signal, as well as phase and intensity errors in MZ branches. The proposed MPL system configuration exhibits significant performance and it will have great impact on aerospace, radar, and satellite-to-ground downlink communication system applications.
