An intracavity CO_2 laser is reported,which is polarized by complex(hollow dielec-tric cylindrical and metallic parallel-plate)waveguides and arrives at 98% polarization,95% po-wer stability,fundmental mode output at 7-9 watt.
Inclusion of the optimized composite waveguide concept in the InGaAsP/InP PBMR laser construction resulted in an improvement of the differential quantum efficiency value by more than ten per cent.
Measurements have been done in the millimeter wave region on a composite waveguide which comprises a dielectric rod waveguide connecting two metal rectangular waveguides.
Optically transparent polyimide : titanium dioxide (TiO2) composite waveguide materials were prepared by the dispersion of nano-sized TiO2 particles into polyimide.
The solution was coated on a glass substrate, and a polyimide : TiO2 composite waveguide (4 wt% TiO2 concentration) was successfully produced after the heat treatment.
Uniform dispersion equations are obtained which make it possible to trace the transition of eigenvalues and eigenfunctions of two waveguides separated by an impermeable barrier into the eigenvalues and eigenfunctions of the composite waveguide.
Organization of "electrodynamic assemblage" in calculation of complex waveguide objects
Sections of such waveguides are elements of complex waveguide connections that are used to construct microwave digital telecommunications circuits built on rectangular waveguides partially filled with dielectric.
It is shown how more complex waveguide geometries such as fibres with a D-shaped cross-section may be assessed by the finite-difference method combined with perturbation analysis.
As demonstrated with a practical example, the APSS-WM is a powerful and efficient tool for designing a complex waveguide.
