Summary :

Experimental study of the near field distribution around the dielectric waveguide end has been carried out on the microwave region. The result will be used for detail discussion of reflection, deflection and radiation phenomena of electromagnetic wave in the integrated circuit of microwave through optical wave regions. Transverse component of the near field is picked up by a movable small antenna and detected by a network analyzer with a reference signal. The measured results are separated into amplitude and its phase, and expressed by both equi-amplitude, equi-phase contour maps. From the experimental study, followings are resulted: (1) At the tilted type end, the near field in front of the facet is bent toward an apex of the guide end. (2) Measured equi-phase contours clearly show the direction of local power flow around the guide end. (3) In the equi-phase contours, there are several points where the contour lines concentrate each other. These points correspond to minimum amplitude position. At that point the electromagnetic energy is circulating. (4) Equivalent reflection coefficient of a guide mode at the end facet can be determined by the phase distribution of a standing wave field on the guide.
