In this paper, a compact broadband bandpass filter with wide out-of-band rejection characteristics based on halberd-shaped spoof surface plasmon polariton (SSPP) is proposed.

Compared with the traditional dumbbell-shaped SSPP, the halberd-shaped SSPP has good slow-wave property, and the designed bandpass filter based on halberd-shaped SSPP can achieve a more compact size.

Hong-Ou-Mandel (HOM) interference is a non-classical effect of photons and plays an important role in quantum optics. The <i>β</i>-barium borate (BBO) has a high nonlinear efficiency, and is commonly used to generate biphoton states, thereby exhibiting HOM interference. However, in previous experiments, researchers often used band-pass filters, so the resulting spectrum was directly determined by the band-pass filter. As a result, the original spectrum of the BBO crystal, especially the spectrum under tight focusing, was lack of systematic research. In this paper, the biphoton spec

Abstract:

With the rapid development of emerging technologies such as multimedia services, live broadcasting, video conferencing, and high-definition television, traditional radio frequency communication has been unable to meet people's growing demand for communication capacity and transmission rate. In recent years, optical communication has received extensive attention from the industrial and scientific communities due to its advantages of large bandwidth, high speed, low power consumption, light weight and strong anti-interference ability. As an emerging light source, the optical frequency comb (OFC)

Abstract:

In order to reduce power, realize ultrafast response time and dynamic tunability, a plasmonic waveguide system based on four disk resonators is designed. A plasmon induced transparency effect is theoretically analyzed using two different methods:one is the direct destructive interference between bright and dark mode resonators, and the other is the indirect coupling through a plasmonic waveguide. Due to the giant effective nonlinear Kerr coefficient of the graphene-Ag composite material structure and the enhancement characteristics of slow light response to optical Kerr effect, the pump intens

Abstract:

Spintronics is a new type of electronics based on electron spin rather than charge as the information carrier, which can be stored and calculated by regulating and manipulating the spin. The discovery and application of the giant magnetoresistance effect opened the first door to applying electron spin properties. Realizing on-demand control of spin degrees of freedom for spin-based devices is essential. The two-dimensional novel material, monolayer transition metal dichalcogenides (TMDs) (MoS<sub>2</sub> is a typical example from the family of TMDs materials), has become an excelle

Abstract:

Terahertz (THz) waves usually refer to electromagnetic waves with frequencies between 0.1 and 10 THz.It has potential applications in wireless communication,biomedical image processing,nondestructive testing,military radar and other fields.However,due to function limitation of the natural materials,multifunctional terahertz devices are difficult to design and fabricate,which become a bottleneck for THz technology.The emergence of metamaterials fills a gap in the electromagnetic materials in the THz frequency band,and is widely used in THz functional devices,such as THz modulators,THz absorbers

Abstract:

ObjectiveThe objective of this presentation is to describe the new word alertcapability in ESSENCE and how it has been used by the FloridaDepartment of Health (FDOH). Specifically, this presentation willdescribe how the word alert feature works to find individual chiefcomplaint terms that are occurring at an abnormal rate. It willthen provide usage statistics and first-person accounts of how thealerts have impacted public health practice for the users. Finally,the presentation will offer future enhancement possibilities and asummary of the benefits and shortcomings of this new feature.Introduc
