Quantum key distribution (QKD) enables two authenticated parties to establish identical secret keys with information-theoretic security grounded in quantum mechanics. Since the original BB84 protocol ...

Abstract: Nowadays, with the continuous development of science and technology, people's requirements for ranging accuracy and detection speed are also increasing. Based on the principle of frequency ...

Key Laboratory of All Optical Network & Advanced Telecommunication Network of EMC, Institute of Lightwave Technology, Beijing Jiaotong University, Beijing, China. As early as the 1980s, optical ...

As a special kind of ultrashort optical pulse, optical frequency combs (OFCs) have important applications in various fields, ranging from examining the theory of quantum electro-dynamics [1, 2], space ...

We present a novel approach for triangular-shaped waveform generation by applying optical single sideband (OSSB) modulation and optical carrier suppression (OCS) modulation to an input signal. Firstly ...
