New Measuring Method of Ezamination of Planar Optical Waveguides

摘要：

A new method of mode spectrum measurement in planar waveguides is presented. The described end-fire mode spectroscopy technique exploits the difference of refraction angles of different modes skew-incident to the output face of the waveguide. This method provide reliable measurements of the whole mode spectra in any planar waveguides including step-index waveguides with thick cover layers and deep-buried graded-index waveguide structures. Furthermore, the technique allows conducting direct measurements of the maximal refractive index in arbitrary graded-index waveguides as well. Results of the comparative experiments performed by the end-fire mode spectroscopy and other techniques prove a feasibility of the developed method.
