“…Ink-jet technology has been used to “write” refractive microlenses, and waveguides 28 29 using optical epoxies, with the key advantage that they can be fabricated directly onto optical components of arbitrary geometry. 30 31 32 Refractive microlens configurations which may be printed using ink-jet processes range from convex/plano hemispherical, hemi-elliptical and square 33 to convex-convex. Arrays of thousands of microlenses have been inkjet printed for use as free-space optical interconnects in VCSEL-based photonic switches, 34 with 13,872 lenslets being printed on a single wafer.…”

Applications of microfluidics and MEMS (micro-electromechanical systems) technology are emerging in many areas of biological and life sciences. Non-contact microdispensing systems for accurate, high-throughput deposition of bioactive fluids can be an enabling technology for these applications. In addition to bioactive fluid dispensing, ink-jet based microdispensing allows integration of features (electronic, photonic, sensing, structural, etc.) that are not possible, or very difficult, with traditional photolithographic-based MEMS fabrication methods. Our single fluid and multifluid (MatrixJet™) piezoelectric microdispensers have been used for spot synthesis of peptides, production of microspheres to deliver drugs/biological materials, microprinting of biodegradable polymers for cell proliferation in tissue engineering applications, and spot deposition for DNA, diagnostic immunoassay, antibody and protein arrays. We have created optical elements, sensors, and electrical interconnects by microdeposition of polymers and metal alloys. We have also demonstrated the integration of a reversed phase microcolumn within a piezoelectric dispenser for use in the fractionation of peptides for mass spectrometer analysis.

“…To integrate these spherical microlens arrays with GRIN lenses in a manufacturable way a special deposition technique called "Drop-on-demand microjet printing" will be used [23,24] (see figure 6). With this technique micro-droplets of optical polymeric materials, measuring 25-50 µm in diameter, can be dispensed at temperatures up to 220°C onto optical substrates and components to create precision-placed refractive microlenses with diameters ranging from 40 to 1000 µm.…”

In this paper we present different configurations for a compact free-space optical interconnection (FSOI) module by combining two radial gradient refractive index lenses (GRIN) and/or two arrays of refractive microlenses. Based on our findings with ray-tracing and radiometric analysis we discuss how we have selected the proper optical system configurations and how we have chosen the different design parameters to optimally accommodate different types of opto-electronic emitters such as LEDs, micro-cavity LEDs and VCSELs. We hereby focused on maximizing optical coupling efficiencies and misalignment tolerances while minimizing inter-channel cross-talk. Furthermore we discuss the experimental optical characteristics of two such prototype modules that we completed together with the first experimental results of their use in parallel data communication demonstrator systems.
