Creation of backdoors in quantum communications via laser damage

, 2016
Practical quantum communication (QC) protocols are assumed to be secure provided implemented devices are properly characterized and all known side channels are closed. We show that this is not always true.

Switchable Bandpass/Bandstop Filter Using Liquid Metal Alloy as Fluidic Switch

Sensors, 2019
In this paper, we propose a switchable band-pass/band-stop filter using liquid metal alloy as a fluidic switch. The filter is designed based on the Chebyshev response and implemented using a three-stage quarter-wavelength resonant structure.

Generation of heralded single photons beyond 1100 nm by spontaneous four-wave mixing in a side-stressed femtosecond laser-written waveguide

, 2015
We demonstrate a monolithically integrable heralded photon source in a femtosecond laser direct written glass waveguide. The generation of photon pairs with a wide wavelength separation requires a concomitant large birefringence in the normal dispersion ...

A Compact Dual Bandpass Filter Using Dual Composite Right-/Left-Handed and Open-Loop Ring Resonators for 4G and 5G Applications [PDF]

Radioengineering
In this paper a very compact design of a dual-band band pass filter (D-BPF) using dual composite right-/left-handed (D-CRLH) and open-loop ring (OLR) resonators is presented. To overcome the frequency ratio limitations of D-CLRH resonators technique, the

Monolithically-Integrated Bandpass Filters Using Capacitively-Loaded Intertwined Helical Resonators

IEEE Journal of Microwaves
This paper presents a novel compact 3D bandpass filter (BPF) concept based on new classes of intertwined helical resonators. The concept is demonstrated by three unique RF filter architectures: a second-order single-band BPF, a second-order dual-band BPF,

Compact tri‐wideband bandpass filter with multiple transmission zeros

ETRI Journal, 2018
This paper presents a tri‐wideband bandpass filter (TWB‐BPF) with compact size, high band‐to‐band isolation, and multiple transmission zeros (TZs). The proposed TWB‐BPF is based on a multiple‐mode resonator (MMR), which is interpreted by the method of ...

Transversal wideband bandpass filter with a wide stopband and multiple transmission zeros

ETRI Journal, 2020
Herein, we present a compact transversal bandpass filter (BPF) with an extremely wide upper stopband and multiple transmission zeros (TZ). Three signal transmission paths with shorted stubs and open‐coupled lines allow signal transmission from input port
