THEORY AND PROPERTIES OF QUASIWAVEGUIDE MODES

A theory is developed to explain the origin of physical phenomena in q uasiwaveguide, based on the forward scattering and multiple-wave inter ference effects. The properties of quasiwaveguide modes, such as posit ions, linewidths, the reflectivity of the reflected light spot, and th e reflectivity distribution of scattered light are described. The shap e of the m-lines is derived theoretically. Applications of the theory are also discussed. (C) 1996 American Institute of Physics.
