It is generally recognized by the optics in computing community that photonic technologies can help to alleviate the data communication bottlenecks of future digital processing systems in two ways. In a first approach optics could be used as a wirereplacing technology at the different interconnect levels in computers such as the back-plane, the board-to-board, the multi-chip to multi-chip (MCM) and even the intra-MCM interconnect level. In a second approach 2D-arrays of smart pixels, which are integrated VLSI-photonic components that combine the electronic processing power of Si-CMOS with the high interconnect density of GaAs-based parallel opto-electronic I/O planes, could play a major role in dedicated processing systems such as smart focal-plane arrays, artificial retina and early-vision processors and outperform their dedicated all-electronic counterparts. In this paper we bring forward some of the multifarious ways to put micro-optical components to work in digital optical information processing systems by reviewing two of our most recent proof-of-principle demonstrators. First we will illustrate the "microoptics as a wire-replacing technology" paradigm by presenting a micro-optical module for multi-channel free-space intra-MCM interconnects. Secondly, as an example of the so-called "smart pixel" paradigm, we demonstrate how we have constructed a prototype morphological image processor based on 8x8 arrays of opto-electronic transceiver arrays
