title = "Noise analysis in coherent phase demodulated analog photonics transmission link under different power levels",
abstract = "We report a phase modulation coherent linear phase demodulation (PM-CLPD) analog photonic link (APL) based on an optical phase-locked loop (OPLL). In this work, we mainly focus on the analysis for the impact of different noise sources on the noise floor in particular under different received optical powers. It was found that due to the limited commonmode noise rejection of the balanced detector, an appropriate received optical power should be made of choice in order to prevent the potential dynamic range deterioration. With this scope, experimental investigations have been carried to verify such specified condition at certain system configurations. In addition, to solve the problem of noise deterioration caused by optical amplification in traditional APL, a common optical amplification scheme is incorporated to facilitate the common-mode noise reduction, making the system less sensitive to the extra noise induced deterioration. By taking into account these aspects, an improvement as large as 10dB is demonstrated for the overall system noise floor.",
