ABSTRACT:
An arrangement for an integrated optical spectrometer having an optical film waveguide and a focusing optical grating with grating lines extending perpendicular to a plane of the film waveguide characterized by the grating having a fixed grating constant so that adjustment and contrast problems can be avoided. The new arrangement can take the form of a film waveguide in coaction with a ribbed waveguide disposed thereon, with the grating being formed in the edges of the ribbed waveguide.
