ABSTRACT:
A waveguide input/output device for input and output of laser light L into a thin-film waveguide 2 via an input grating or prism 7 and an output or emission grating 8. The height of the emission grating 8 is gradually increased in a travel direction of a light advancing through the waveguide and either the height of the input grating 7 or the height of the output grating 8 is gradually increased in the direction of propagation of the service elastic waves in the waveguide 3 generated by a transducer element 3.
