High-speed operation of free-space optical interconnect for a three-dimensional optoelectronic crossbar switching has been analyzed. System architecture, transmitter and receiver design are presented. The effect 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 has been analyzed. The 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.
