Abstract
Microwave photonic link (MPL) allows high-fidelity transmission of broadband analog signals over long distances using fibers. In this paper, we present a balanced MPL using a low-Vπ thin film lithium niobate (TFLN) modulator and a high-power modified uni-traveling carrier balanced photodiode. Due to relative intensity noise (RIN) suppression from the balanced detection scheme, shot noise limited link performance is theoretically modeled and experimentally characterized at >40mA photocurrent. Using this link, we also demonstrated positive link gain, <15dB link NF and ~20GHz bandwidth.
