With designing air pads on silicon-on-insulator (SOI) wafer periodically as a cellular structure, a 1×2 photonic band gap (PBG) beam splitter is proposed in this article . We study the characteristics of the designed 1×2 SOI PBG beam splitter and simulate the relationship of the two output power with the launching wavelengths. We use finite-difference-time-domain (FDTD) as simulation technique....

High-power applications of rf often require the use of overmoded waveguide to reduce the probability of rf breakdown by lowering surface fields, as well as to reduce the attenuation due to ohmic losses in transporting the power from the point of generation to the point of use. This is particularly true in the development of warm linear collider designs, such as NLC, JLC, and CLIC, especially th...

1550-7998=20 The beam splitter in high-power interferometers is subject to significant radiation-pressure fluctuations. As a consequence, the phase relations which appear in the beam splitter coupling equations oscillate and phase modulation fields are generated which add to the reflected fields. In this paper, the transfer function of the various input fields impinging on the beam splitter fro...

This research focuses on fabrication of 1 by 12 multimode polymethyl methacrylate based step-index polymer optical fiber (PMMA SI-POF). This home-made bundled-fiber splitters have been fabricated by a Distinctive technique. There several systems available on the market, which able to split or couple optical signals transmitted into some different channels, which are all afflicted with certain d...

The terahertz (THz) frequency region of the electromagnetic spectrum is located between the traditional microwave spectrum and the optical frequencies, and offers a significant scientific and technological potential in many fields, such as in sensing, in imaging and in spectroscopy. Waveguiding in this intermediate spectral region is a major challenge. Amongst the various THz waveguides suggest...
