A Waveguide to Unenclosed Coplanar Waveguide Transition
IEEE Transactions on Microwave Theory and Techniques, 2010A transition from rectangular waveguide to unenclosed coplanar waveguide (CPW) is designed and tested at W -band. Full-wave finite-element analysis is applied to the design and optimization trends are shown for the critical parameters. A stepped-impedance filter suppresses a parasitic mode, which is generated as the circuit emerges from the waveguide ...

Dielectric Waveguides and Waveguide Devices for Microwave Applications
4th European Microwave Conference, 1974, 1974A survey on the state of the art in Dielectric Waveguide (DW), stressing in particular the practical microwave applications, is given. The principles for designing DWs, fixing and joining devices, launchers, various multiport networks etc. are founded. A simple theory to calculate parameters of multiport networks with distributed coupling is developped.

Much of the discussion in the previous three chapters centered around lossless transmission lines. For these lines, the various relations were independent of conductivity of the materials involved. In fact, even for a distortionless transmission line, although an attenuation constant was present, all other basic properties of the line were independent ...

Ion implanted waveguides and waveguide lasers
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1992Abstract Ion implantation is an accurate method for modifying the refractive index of surfaces of insulators to form optical waveguides and waveguide lasers. Alternative approaches are to directly define the waveguide region by implanting chemical dopants to control the refractive index and the lasing transitions or to use ion beam induced damage ...

Waveguide dispersion in anisotropic optical waveguides
Soviet Journal of Quantum Electronics, 1987The method of shift formulas is employed to obtain approximate analytic expressions which can be used to calculate?with sufficient accuracy for practical applications?the waveguide and polarization dispersion of the dominant orthogonally polarized modes in anisotropic optical fiber waveguides.

, 1982 The optical waveguide is the fundamental element that interconnects the various devices of an optical integrated circuit, just as a metallic strip does in an electrical integrated circuit. However, unlike electrical current that flows through a metal strip according to Ohm’s law, optical waves travel in the waveguide in distinct optical modes.

The waveguide coupler between fiber and slab waveguide
2017 18th International Conference on Electronic Packaging Technology (ICEPT), 2017For the past few years, optical interconnects technology has been developed rapidly. At the same time, many problems and difficulties need to be solved immediately. There is a difficult problem in optical coupling that the coupling efficiency between fiber and slab waveguide is quite low.
