Abstract

We present a linearized phase-modulated analog photonic link that utilizes parallel interferometric demodulation to suppress the third-order intermodulation distortion present in the link. By utilizing two parallel interferometers with different differential delays, we are able to balance the third-order distortion in the output photocurrent and achieve a fifth-order limited link response. We demonstrate shot noise-limited spurious-free dynamic ranges of ${\sim 130} $ dB (1-Hz bandwidth) at ${\sim 1} $ GHz for a total DC photocurrent ${I_{dc}}\sim 8 $ mA and ${\sim 131} $ dB (1-Hz bandwidth) at ${\sim 5} $ GHz for a total DC photocurrent ${I_{dc}}\sim 7 $ mA. These results represent a nearly two order-of-magnitude improvement in dynamic range over conventional intensity- or phase-modulated analog photonic links for a fixed received photocurrent.
