Periodic Structures for Integrated Optics

This paper deals with the theory and device applications of periodic thin-film waveguides. Topics treated include mode solutions, optical fiiters, distributed feedback lasers (DFB), distzibuted B r a g reflector (DBR) lasers, grating couplers, and phase matching in nonlinear interactions.

Periodic structures in integrated optics

Thin-film dielectric waveguides with a periodic refractive index, a periodic substrate, or periodic surface are studied. The field is determined from Maxwell's equations using Floquet's theorem. The Brillouin diagram and the interaction regions are investigated. The bandwidth and the attenuation coefficients of the interaction regions are given as a function of the optical wavelength. A number ...

Complementary Periodic Structures for Miniaturization of Planar Antennas

In this paper various layered planar periodic structures which provide miniaturization of planar antennas are proposed and discussed. The proposed designs are based on two concepts, reactive impedance surfaces and complementary periodic structures. In the proposed structures, complementary periodic rings and slots are patterned on the intermediate boundaries of the dielectric layers. A patch an...
