In this article the performance of grey‐coded advanced optical modulation formats is evaluated on a single‐channel high‐speed long‐haul optical communication link and are …
Using time-adaptive probabilistic shaped 64QAM driven by a simple SNR prediction algorithm, we demonstrate> 450 Gbps transmission over a 55-m free-space optics link with …
In this paper, we propose an optical transmission system of 128 quadrature amplitude modulation for dense wavelength division multiplexing. In such a system, Gaussian optical …

In order to ensure the security of the local oscillator (LO) in continuous variable quantum key distribution (CV-QKD), the LO in CV-QKD based on the local LO (LLO) scheme no longer …
We experimentally demonstrate the first on-chip broadly-tunable RF scanning receiver, using silicon photonic technology. By exploiting an innovative and simple noise-cancelling …
