Abstract

We introduce three crosstalk models in lens-based free-space optical interconnects systems. In these models, we use the Gaussian beams as the information carriers. In the first and the second models, the resulted finite integral of the optical field at the detectors plane was solved by expanding the lens’ finite aperture in terms of complex Gaussian functions and in terms of an infinite series of Bessel functions, respectively. In the third proposed model, the resulted finite integral was solved by approximating the Gaussian function in the integrand by zeroth-order and first-order Bessel functions without the need to expand the aperture function. We show that the third proposed model compares favorably with the other models with superior computational efficiency.
