Optical communications systems are continuously miniaturized to integrate several previously separate optoelectronic devices, organized with silicon-based incorporated circuits, onto a distinct substrate. Modulators and photodetectors have essential roles in photonic operate different mechanisms. Integrating them into one device is complex challenging, but these multifunctional devices numerous advantages. This article uses graphene/hBN-based structure modulate, detect, absorb any signal the...
In this paper, a novel Graphene Plasmonic Grating modulator is composed of four-layer graphene, encapsulated in hBN layers, and merged with Fabry-Perot (FP) cavity presented. The main aim graphene the proposed to tune FP cavity's resonant frequencies. Standing electric field waves induced by interferometer are strongly formed at top grating, where hBN/graphene layers established. Therefore, propagation surface plasmon polaritons (SPPs) on sheets confines between layer gratings, causing high...
Abstract Total knee arthroplasty (TKA) improves patients’ Health-related quality of life (HRQoL) compared to before surgery. However, based on our knowledge, the improvement in HRQoL after TKA, which depends various factors, has yet be investigated healthy people. This study aimed evaluate patients people and factors affecting TKA. In this matched case–control (1002 participants), 501 who underwent TKA between 2015 2022 at Shafa Yahyainan Hospital affiliated with Iran University Medical...
One of the most important aims designing building's facades, in addition to maintaining its durability and sustainability against severe weather conditions, is beauty attractiveness appearance overall adaptation urban context system. Because a building alone, no matter how beautiful it is, ultimately compared adjacent buildings. These days, with little surfing top areas Tehran other metropolitan Iran, we will encounter seemingly aristocratic buildings, which called "Roman Facade". This...
Real-time detection and generation of single microwave photons would be important in many quantum technology applications. For single-microwave-photon sources, much the groundwork has been done already within framework circuit electrodynamics (cQED) frequency range 4 GHz – 8 GHz. However, currently there are no detectors that can reliably resolve photon events, unlike at optical frequencies. In June 2013, we started a joint research project to develop both sources working single-photon level...
