Abstract

Free-space digital optics is a new technology that exploits the ability of optics to handle thousands of light beams or information channels at once. This and other features of optics complement the strengths and weaknesses of purely electronic systems. A compact free-space optical system that uses array of microlens for chip-to-chip and board-to-board interconnections is proposed. Here the weakly diffracted Gaussian beam and wavelength division architecture are utilized to improve the channel density and reduce the crosstalk in a microlens interconnection system. Based on the simulation, we improve the channel capacity by 3.47 times (or reduce the crosstalk by 93.1 dB) while maintaining the same crosstalk (or channel density) compared with the conventional microlens interconnection system. As for the nonperfect filtering effect of different wavelengths at the detector plane, it is also studied to fully investigate the properties of the proposed scheme. The parameter sensitivity of the proposed system is studied for completeness. From the simulations, the relationship between the interconnection distance and spot size at the detector plane is wavelength-independent. In addition, the spot size is the most sensitive to the change of the microlens diameter compared with the other system parameters.
