Abstract :
Fresnel lenses in optical waveguides have been designed, analyzed, and experimentally fabricated and evaluated in BaO waveguides. Diffraction limited spot size, 18 dB of the signal-to-noise ratio, angular field of view of 15°, and 23 percent diffraction efficiency have been observed experimentally. Limitations of and methods for improving its performanee are discussed.
