In this work, we demonstrate a cascaded ring resonator based wide stop-band filter. The filter consists of four cascaded rings and a bus waveguide. The first ring has a radius of 7μm, the second, third and the fourth rings have radius of 7.01 μm, 7.02 μm,

The linear active disturbance rejection control (LADRC) method has been proven to be effective for overcoming various system with uncertainties, but its high-gain characteristic is very sensitive to the output noise. So for a class of uncertain nonlinear

A filtering patch antenna with reflectionless in a wide frequency range
Microwave and optical technology letters (Print), 2023A filtering antenna consists of a reflective filtering antenna (RFA) and a bandstop filter (BSF) is presented. Due to the L‐shaped feeding structure, slots etching on the radiator and the ground plane, the RFA obtains good impendence matching, stable in ...

Temperature-compensated high-sensitivity relative humidity (RH) sensor based on bandpass filtering and Vernier effect is proposed. The sensor with Vernier effect is formed by the cascading single-mode fiber (SMF)-hollow-core fiber (HCF)-SMF structure and

The Vernier effect of two cascaded in-fiber Mach-Zehnder interferometers (MZIs) based on a spherical-shaped structure has been investigated. The envelope based on the Vernier effect is actually formed by a frequency component of the superimposed spectrum,

A simple method of alternatively using high-inversion and moderate-inversion erbium-doped fiber amplifiers (EDFA's) in an optical amplifier chain is presented to mitigate the self-filtering effect and equalize both signal power and signal-to-noise ratio (

3.6-Tbps Duobinary 16-QAM Transmission with Improved Tolerance to Cascaded ROADM Filtering Penalty
European Conference on Optical Communication, 2018We successfully demonstrate 3.6- Tb/s 9-channel duobinary 16-QAM transmission over 1700-km link impaired by cascaded ROADMs. With improved tolerance to the narrow filtering effect, the duobinary shaped QAM extends the reach by 27% compared to the ...

A Cascaded Resonator Decoupling Network for Two Filtering Antennas with Adjacent Operating Bands
European Conference on Antennas and PropagationIn this paper, the mutual coupling problem between two adjacent-band filtering antennas is addressed. A coupled-resonator decoupling network (DN) is co-designed with the coupled filtering antennas with little effect on the original filtering responses ...
