Paper Abstract

A design and a fabrication of multiple beam generators using zone plate array are reported, considering intensity distribution of a Gaussian beam. A multiple beam generator is composed of 10 X 10 circular zone plates with 5 kinds of zone radius ranging from 0.42 mm to 0.85 mm, considering intensity distribution of a Gaussian beam. The focusing characteristics are examined at 0.78 micrometers in wavelength of LD under normal incidence condition. The focusing intensity nonuniformity was corrected such that 10 multiple focusing spots with relative intensity fluctuation less than 20% were achieved. Feasibility of application to high speed opto-electronic integrated circuit is discussed.
