“…The balance heterodyne detection overcomes the disadvantage of low utilization rate of local oscillator in single tube detection, which allows that the coherent optical communication receiver obtains high sensitivity and SNR at lower local oscillator power. The balance heterodyne detection can also effectively suppress the interference of common mode noise and improve the SNR of coherent optical communication system close to the quantum noise limit level [4]. The double balance detection technology was developed by Kuwaharra et al on the basis of the balance detection theory in 1987.…”

This paper introduces the working principle of the balanced heterodyne detection system, establishes the corresponding mathematical model, deduces the signal to noise ratio (SNR) formula of the balanced heterodyne detection. By comparing balance heterodyne detection with general coherent detection with MATLAB numerical simulation, the superiority of balance heterodyne detection system is proved theoretically. Finally, the simulation models of ordinary heterodyne detection, balance detection and double balance detection system are built by OptiSystem. The simulation results are consistent with the conclusions derived from the mathematical analysis, which provides a new method for the research of weak laser detection technology.

“…By scanning the frequencies of the OFC, the input RF signal can be down‐converted to a given intermediate frequency (IF) band. However, when a two‐tone signal is received, the nonlinear response of a modulator may introduce inter‐modulation distortion (IMD), which is not suppressed in [3]. Another scheme for photonic receiving and linearisation of RF signals has been proposed in [4].…”

“…Many photonic‐assisted down‐conversion techniques have been proposed for RF receiving. We have recently demonstrated a scheme for coherent RF scanning receiving based on a flat optical frequency comb (OFC) [3]. By scanning the frequencies of the OFC, the input RF signal can be down‐converted to a given intermediate frequency (IF) band.…”

A scheme for simultaneous down-conversion and linearisation of radio-frequency (RF) signals is proposed and demonstrated. Based on carrier-suppressed double-sideband modulation, the input RF signal can be down-converted to any intermediate frequency (IF) tone in the range of 8-12 GHz. Compared with the down-conversion scheme with two cascaded intensity modulators, the proposed scheme has improvement of >21 dB of the suppression ratio of third-order intermodulation distortion and 6.17 dB of spurious-free dynamic range.
