Tube waveguideChirped gratingTransmission spectraTHz sensingMulti-layer hollow-core PMMA tube waveguides with varying grating structures were theoretically and experimentally investigated for the terahertz (THz) chemical material sensor applications. Compared with single-layer tube, the multi-layer cases can ...
An optical network is formed of multiple H-tree distribution devices, separated into different waveguide layers. The optical network receives an input optical signal, such as an optical clock signal, and makes duplicate copies of that input signal. The duplicate copies are routed through the ...
Gapwaves CEO Jonas Ehinger comments:“Bringing the MLW technology to the market is a new milestone towards making Gapwaves the standard for waveguide-based radarantennas. Continuing the work of Metasum AB, which originally developed MLW, we can now offer our customers sol...
由平版印刷术形成的、使用低传播损耗聚合材料的单模光波导。 Formed by the lithography, the use of low propagation loss single-mode waveguide polymeric material. 该光波导具有衬底(2),介于衬底表面上的、折射率为n The optical waveguide having a substrate (2), b
with return loss at 30 dB. Since this is the loss of the feeding FGC waveguide lines, the two sets of vias and the midsection of FGC waveguide line, the loss due to the lines may be calibrated out to estimate the loss due to one vertical interconnect. At 90 GHz, the loss ...
A multi-layer laterally-confined dispersion-engineered optical waveguide may include one multi-layer reflector stack for guiding an optical mode along a surface thereof, or may incl
