Paper Abstract

Ill this experimental study we investigate the guided mode-radiation mode coupling of periodic dielectric waveguides. The dispersion relation and the attenuation constant along the dielectric waveguide were measured around the second Bragg frequency. The far field radiation pattern was also measured. Floquet theorem was applied to solve wave equations. Zero order approximation was used in the design of waveguides. For surface emitting structures used in surface emitting lasers and couplers, the most important parameter is the dispersion relation and attenuation constant along the corrugated waveguide around the second Bragg frequency. The dispersion and attenuation measurement shows that the attenuation constant minimum occurs at the second Bragg frequency. This corresponds to the maximum Q point of the corrugated waveguide. Two side incidence shows that in the out of phase condition the radiation power is minimum at the second Bragg frequency and have two lobes.
