Abstract:

During the third year FY82, a great deal of progress was made in the experimental investigation of chirped grating lenses on glass and LiNbO3 waveguides. Efficiency as high as 70 has been demonstrated in LiNbO3 using deposited TiO2 on Ti-indiffused waveguides and doubly ion exchanged LiNbO3 in benzoic acid. Properties of chirped grating lesnes affected by the waveguide parameters, higher orders of diffraction and substrate mode conversion have been evaluated.
