Robust reconfigurable radiofrequency photonic filters based on a single silicon in-phase/quadrature modulator. [PDF]
Nanophotonics, 2023 Abstract Combining integrated photonics and radiofrequency (RF) signals in the optical domain can help overcome the limitations of traditional RF systems. However, it is challenging to achieve environmentally insensitive filtering in wireless communications using integration schemes.

Coexistence of quantum key distribution and optical communication with amplifiers over multicore fiber. [PDF]
Nanophotonics, 2023 Abstract In this paper, the influence of classical signals on quantum key distribution (QKD) is studied over multi‐core fiber (MCF) when optical amplifiers exist. Firstly, the long‐distance simultaneous transmission architectures of QKD and classical signals are proposed based on advanced asymmetric sending or not sending QKD (SNS‐QKD) and classical ...

Novel circulator design using substrate integrated coaxial line
Electronics Letters, Volume 59, Issue 15, August 2023., 2023 The contribution of this work is to propose a novel circulator design using the substrate‐integrated coaxial line (SICL) structure. The proposed SICL circulator allows the 3‐D waveguide circulator to be built in a planar form using the printed circuit board (PCB) technology.

Combined signal‐interference/split‐type microwave multi‐band bandpass filters
IET Microwaves, Antennas &Propagation, Volume 17, Issue 7, Page 583-593, June 2023., 2023 Two classes of RF/microwave planar quad‐band bandpass filters (BPFs) that simultaneously exploit transversal signal‐interference and multi‐passband‐splitting mechanisms are reported or for experimental–demonstration purposes, two microstrip prototypes are developed and tested. Besides, as a further application, a two‐layer balanced‐circuit version with

International Journal of Antennas and Propagation, Volume 2023, Issue 1, 2023., 2023 We propose bandpass filters (BPFs) with mixed electromagnetic coupling paths (MEMCPs) that comprise two coupled vertical split‐ring resonators (VSRRs) and present the equivalent circuit models of the coupled VSRRs. We demonstrate that the dominant coupling modes for the top and bottom layers of the VSRRs are magnetic (M) and electric (E), respectively,
