Article Abstract
A multi-wavelength bandstop filter is proposed and numerically demonstrated using the sum-frequency generation (SFG) process in a waveguide of periodically poled lithium niobate (PPLN). This proposed device achieves channels number reconfigurable, central filtering wavelength of each filtering channel independently tunable and extinction ratios (ERs) equalized via all-optical methods.

The microwave photonic filter (MPF) has emerged as a promising candidate for next-generation radio-frequency (RF) applications, offering exceptional performance in terms of large instantaneous bandwidth, ultra-wideband frequency tuning, and multifunctionality. However, most existing MPFs provide only a single output port, limiting their applicability in scenarios requiring simultaneous multi-channel responses. Here, we demonstrate a dual-output integrated microwave photonic filter (IMPF) on the thin-film lithium niobate (TFLN) platform, integrating a Mach-Zehnder modulator (MZM), an add-drop microring resonator (MRR), and a notch MRR.

To address the demand for wideband, dynamically controllable filtering characteristics in radomes, a plasma composited frequency selective surface (PC-FSS) structure with broadband, active filtering properties is proposed and experimentally demonstrated. Initially, a broadband band-pass FSS was designed using a multilayer cascade method and integrated with inductively coupled plasma (ICP) to form the PC-FSS. The effects of various discharge conditions-including pressure, power, and ICP thickness-on the parameter distribution and filtering performance of the PC-FSS were investigated through experimental measurements.

This paper presents a nonvolatile switchable dual-functional THz metamaterial with selective transmission and adjustable absorption based on quasi-bound states in the continuum (q-BICs), where the q-BICs are achieved through periodically arranged silicon disks tetramer. By introducing asymmetry perturbation through manipulating the radii of diagonal silicon disks of the proposed THz metamaterial, resulting in the transition from symmetry-protected bound states in the continuum (SP-BICs) to q-BICs.

The design comprises nine split-ring resonators, organized into three groups of three same radius. The radius of the groups is 13 µm, 14 µm, and 15 µm, respectively, and are placed between the conductors of a coplanar stripline.
