Abstract

In this paper, a novel method to analyze the crosstalk in parallel free space optical interconnects employing the VCSEL arrays and detector arrays is presented. The light emitted from the VCSEL is calculated based on the structure of laser with distributed Bragg reflectors. The channels are arranged in their position order in the point-to-point interconnects. The beam diffractive propagation induced by the nearest channels is described in the free space. The sign to noise ratio due to the nearest to the tenth nearest channels is calculated.
