Diagnostic Methods for Planar Optical WaveguidesAbstract: Basic diagnostic methods for examining planar optical waveguides, namely the mode spectroscopy for determining the propagation constants of waveguide modes and two methods for measurement of attenuation coefficient of a waveguide or loss in some waveguide components, are presented. A promising advanced method ¢ € ” optical coherence-domain reflectometry ¢ € ” is briefly mentioned.
