This paper presents the modeling of an optical link based on VCSELs. A physics-based model of a VCSEL has been established and validated. The complete optical link has been modeled including free space propagation, Gaussian spatial repartition of light and photodetection. Concerning the photodetection, a low-noise, low-voltage, 2.5Gb/s CMOS photo receiver is being designed, so as to complete the optical link. Furthermore, system parameters such as BER or power consumption can be determined. This results in a fully self-consistent model of a short distance optical interconnection that ca be used to simulate board to board or chip to chip interconnections.
