Microstrip filters are used in frequency converters, frequency multipliers, and branching networks for RF systems.
We present a novel low-loss 3-spot mode coupler to selectively address 6 spatial and polarization modes of a few-mode fiber.
T h e possibility of using a circular electric ( T E 0 i ) mode in circular waveguide has been of considerable interest since t h e initial discovery of its desirable low-loss characteristics (in t
We develop a new design that the perturbation is the minimum when the crossing occurs at the self-image location in a low-loss multimode waveguide.
We develop a new design that the perturbation is the minimum when the crossing occurs at the self- image location in a low-loss multimode waveguide.
We demonstrate for WDM optical networks a wavelength router with substantially reduced losses using a novel waveguide grating design [1].
We propose and demonstrate a design for a lossless rectangular- passband multiplexer with improved passband characteristics.
High optical field confinement-possible silicon waveguides is generally used in various fields.
A thermal oxidation fabrication technique is employed to form low-loss high-index-contrast silicon shallow-ridge waveguides in silicon-on-insulator (SOI) with maximally tight vertical confinement.
We demonstrate low-loss silicon-on-insulator devices for 2-μm or longer wavelengths.
