Low-Bandwidth Photonics-Assisted Receiver for Broad-Bandwidth Wireless Signals

This paper introduces a photonics-assisted receiver that enables the reception of high-bandwidth wireless signals with low-bandwidth electronics. The down-converts input signal into parallel sub-signals, employing photonics-based orthogonal sampling. sampling is based on multiplication and not switching, so, it does introduce additional aperture jitter. Therefore, analog-to-digital converter (ADC) converts higher signal-to-noise-and-distortion ratio (SINAD), which improves Q-factor for detection. improvement especially high, when carried out low-jitter oscillators. Compared to direct detection 30 GHz, simulation demonstrates 2.2 dB enhancement GHz signal, 10 same revealed in experiment 12 4
