The dependence of the spatial distribution of the recorded m-line intensity on the frequency characteristics of a light beam is studied for excitation of waveguide modes in thin-film structures. Semiconductor diodes with emission peaks at 635–670 nm, an He–Ne laser, and light from an incandescent lamp passed through a monochromator are used as light sources with different spectral widths. Thin-film waveguides with high chromatic dispersion are fabricated using multilayer TiO2–SiO2 and ZrO2–SiO2 structures.
