A photonic method of generating dual-band microwave waveforms with simultaneous and different formats is proposed and experimentally verified using a dual-polarization dual-parallel Mach-Zehnder Mo…
The decoy-state method for the quantum key distribution (QKD) is a great countermeasure against the fatal photon number splitting attack. At present, the decoy-state method has been widely employed…
Optical full-field recovery allows for fiber impairments compensation such as chromatic dispersion and polarization mode dispersion (PMD) in the digital signal processing. For cost-sensitive short-…
We present and investigate a scheme to realize fast and precise multi-characteristics extraction and error estimation of Brillouin frequency shift (BFS) simultaneously based on a cascaded feedforwa…
We designed and fabricated a ring-core Bi/Er co-doped fiber (RC-BEDF), and thus investigated the broad-spectrum amplification of orbital angular momentum (OAM) modes. The deviation from the average…
Within a context of C+L band transmission, this work proposes a design approach for Raman pumps in hybrid fiber amplifiers (HFAs) with the goal of maximizing the total system capacity. First, the o…
An integrated fiber-free-space optical (FSO)-fifth-generation (5G) new radio (NR) sub-THz link through a cross-media of 20 km single-mode fiber (SMF), 500 m optical wireless, and 0.5 m RF wireless …
In this paper, we propose to reduce the size of look-up table (LUT) for digital pre-distortion in optical communication using principal component analysis (PCA). In this scheme, the full-size LUT a…
Phase retrieval (PR) schemes based on modified Gerchberg-Saxton (GS) algorithm using pilot symbol or pilot tone have recently attracted great attentions in self-coherent systems. In this work, we p…
The monitoring of electric current is essential to ensuring the reliable operation of power systems and electronic equipment. The present study demonstrates an optomechanical cavity-based resonator…
