Spin waves, and their quanta magnons, are prospective data carriers in future signal processing systems because Gilbert damping associated with the spin-wave propagation can be made substantially lower than the Joule heat losses in electronic devices. Although individual spin-wave signal processing devices have been successfully developed, the challenging contemporary problem is the formation o...

Cylindrical waveguides have a wide range of applications in photonic integrated circuits because lower transmission losses. This paper proposes directional coupler composed cylindrical silicon nanowire waveguide and metal-based hybrid plasmon waveguide. The coupling characteristics the are analyzed theoretically also simulated using finite-difference time-domain method. results show that can op...

Plasmonic metasurfaces form a convenient platform for light manipulation at the nanoscale due to their specific localized surface plasmons. Even despite high intrinsic Joule losses, plasmonic nanoparticles are very effective manipulation. Here, we show lattice of onto dielectric waveguide that efficiently couples oppositely propagating guided modes circularly polarized beams different handednes...

Single–hop WDM networks based on a central Passive Star Coupler (PSC) or Arrayed–Waveguide Grating (AWG) hub have received a great deal of attention as promising solutions for the quickly increasing traffic in metropolitan and local area networks. These single–hop networks suffer from a single point of failure: If the central hub fails, then all network connectivity is lost. To address this sin...

The performance of three optoelectronic structures incorporating substrate-embedded InP-based inverted metal–semiconductor–metal photodetectors and/or volume holographic gratings are analyzed and compared at the primary optical communication wavelengths. These structures, in conjunction with optical-quality polymer layers, can be easily integrated into silicon microelectronic substrates for the...

1098-4402= A Bragg waveguide consisting of multiple dielectric layers with alternating index of refraction becomes an excellent option to form electron accelerating structure powered by high power laser sources. It provides confinement of a synchronous speed-of-light mode with extremely low loss. However, laser field cannot be coupled into the structure collinearly with the electron beam. There...

In this paper, we propose a novel sensor structure based on the rectangular ring resonator with the photonic crystal microcavity (PCM), and optimize the structure using finite-difference time-domain (FDTD) method. This sensor consists of the rectangular resonator with total internal reflection mirror and the PCM, which can be placed at the nearby optical waveguide of the rectangular ring resona...

Chip-scale optical microresonators with integrated planar optical waveguides are useful building blocks for linear, nonlinear, and quantum-optical photonic devices alike. Loss reduction through improving fabrication processes results in several integrated microresonator platforms attaining quality (Q) factors of several millions. Beyond the improvement of the quality factor, the ability to oper...
