WebbA theoretical model based on a novel experiment scheme of dual-channel optical chaotic communication has been presented, and is proved to be reasonable by comparing the numerical simulations with the experimental results. After deducing the transmission function of semiconductor laser by small-signal analysis, how to reasonably select the … Webb13 feb. 2024 · Non-Gaussian receivers for optical communication with coherent states can achieve measurement sensitivities beyond the limits of conventional detection, given by the quantum-noise limit (QNL).
Webb11 nov. 2024 · The photodetection classical theory is generally applied to communication systems working under optical frequencies. The recent development of non-classical theory uses photodetection statistics which require use of quantum theory. The growing interest in quantum detection techniques used in optics-based systems led to the study … Webb30 apr. 2009 · Abstract Communication theory applied to lightwave channels is ordinarily carried out using the semiclassical theory of photodetection. Recent development of nonclassical light sources-whose photodetection statistics require the use of quantum theory-plus increasing interest in optics-based approaches to quantum information …
