Abstract

Performance of free-space optical interconnect for the three-dimensional optoelectronic stacked processor (3DOESP) has been analyzed. The wave propagation in the optical interconnection system has been investigated by utilizing rigorous scalar diffraction theory. The effects of ghost talk caused by the superposition of the delayed reflections of the original signal due to the multiple propagation of the wave between the vertical-cavity surface-emitting laser (VCSEL) and metal-semiconductor-metal (MSM) detector have been analyzed. The conducted study indicates that even in the presence of significant amount of ghost talk a high performance free-space optical interconnect can be realized in this system by employing a receiver architecture that allows for DC level adjustment of the signal at the input of the transimpedance amplifier stage.
