| Outline of Final Research Achievements |
A waveguide type polarization converter is developed, in which a thin metal film is loaded on a substrate or at the interface between the cladding and the air region. No modification to the waveguide core is required, since two asymmetric modes are generated by virtue of the existence of the metal film. The polarization conversion can be obtained for a gold, silver or copper film, provided the configuration parameters are redesigned. Furthermore, the Yee-mesh-based beam-propagation method for a periodic structure is applied to the imaginary-distance procedure with an enhanced amplification factor. The eigenmode analysis of a rectangular hole array is performed with reduced computational time, and the obtained results are utilized to design a polarization converter. A novel configuration composed of two half-wave plates, which are stacked with a inclination angle of 45 degrees has been proposed to obtain the conversion regardless of the polarization plane angle of incident wave.
