Paper Abstract

Special type iodan" diffractive optical coiponents for fiber sodes selection are coaputer-aided designed and generated by digital holography iethods. Kodans are able to contain artificial standards for any given single iode or aultiaodal set. A basic iatheaatical discription is provided for iultichannelled iodans that are usable in fiber couplers, connectors and sultiplexers-deiultiplexers operating under angular iode division. Theoretical aethod of generative function is presented to ensure analytic suuing over aodes with different carrier spatial frequencies. Probles of discretization due to coaputer synthesis is investigated. Special perturbation aethod is provided to evaluate odan's energetic efficiency, selective capabilities and operating accuracy versus discretization step. Two-staged optical systei with generalised sodal spatial frequency plane essential for iode filtering is discussed. It is reported about developient and experisental investigation of gray-level phase iodans .atched to Gauss-Laguerre and Gauss-lleriite iodes.
