Paper Abstract

An optical star coupler which employs holographic optical elements as branching devices is proposed to be applied to bi-directional fiber-optic communication systems with multimode optical fibers and light emitting diodes. Variation of coupling efficiency of the coupler due to the misalignment of optical components and the shift of wavelength is analyzed. The simulated results on the coupler described here show that the efficiency is reduced by 1 dB due to lateral shift of 18 micrometers of optical fibers used for input and output ports. Experimental results of the efficiency variation are explained by the simulation.
