Abstract

It is very helpful to have a special measuring device for examination of planar optical waveguides, which would be applicable both during the waveguide production and trial exploitations. The wanted setup should enable us to determine the transfer functions, attenuation, number of propagating modes, and the synchronous coupling angles for modes of various orders. Such a device has been elaborated and next built in the form of a laboratory setup. Its construction and measurement possibilities are presented below.
