We present an enhanced out-of-plane coupling component for Printed Circuit Board-level optical interconnections. Rather than using a standard 45• micro-mirror to turn the light path over 90• , we introduce a curvature in the mirror profile and incorporate an extra cylindrical micro-lens for beam collimation. Both modifications enable an increase in coupling efficiency and are extensively investigated using non-sequential ray tracing simulations in combination with Matlab optimization algorithms. The resulting design is fabricated using Deep Proton Writing and experimental characterization of the geometrical properties and measured coupling efficiencies are presented.

“…A critical and relatively unsolved issue consists of the efficient coupling of light to and from PCB-integrated waveguides. The most commonly used approach is the use of 45 • micro-mirrors, which are generally directly integrated in the PCB-embedded waveguides (Glebov et al, 2005;Hendrickx et al, 2007;a;Yoshimura et al, 1997). To enhance the coupling efficiency when using waveguide-integrated micro-mirrors, we investigated a pillar-assisted coupling scheme, in which an optical micro-pillar is placed between a surface-mounted laser/detector and an out-of-plane coupling micro-mirror to compensate for differences in thermal expansion of the materials (Glebov et al, 2006).…”

“…In the case of power monitoring on integrated optical components (where only part of the channels need to be terminated) the use of such costly substrates can not be justified and a Si wafer board based hybrid integration approach is preferable. For this purpose, the definition of an out-of-plane coupling structure into the polymeric layer stack is required for which several methods have been reported, including laser ablation [15]- [16], microtoming [17], embossing [18], focused ion beam etching [19], sawing [20], and injection molding [21]. Because of the poor reproducibility or requirement of complicated equipment of these techniques, we have developed a novel integration concept [22] based on a micromachined Si submount with an integrated mirror (Fig.…”

We report on a hybrid integration concept which allows high-density and alignment-tolerant surface mount assembly of top-illuminated photodetector (PD) arrays onto polymeric guided-wave components by means of a micromachined submount with an integrated mirror. This research aims at the development of polymeric waveguide based devices with an embedded optical power monitoring capability for applications in optical fiber communication networks. A prototype integrated multichannel optical power monitor comprising an eight-channel PD module and a polymeric waveguide splitter array was demonstrated which exhibited an average insertion loss of 5.2 dB, a PD coupling efficiency of 02.6 dB, and a crosstalk value of 017.1 dB between adjacent channels. Low polarization and wavelength sensitivity ( < 0.1 dB) was confirmed over a spectral range of 40 nm in both telecom wavelength windows. Index Terms-Hybrid integration, network monitoring and management, optical fiber communication, polymeric waveguide components, silicon micromachining.
