“…R-SOLNET with wavelength filters [11,12,52,53] simplifies the fabrication process of the multi-beam-writing SOLNET. Some of the write beams in the multi-beam-writing SOLNET are replaced with reflected write beams from wavelength filters on edges of the optical devices such as optical fibers, optical waveguides, LDs, photodetectors (PDs), and light modulators.…”

“…Since optical interconnects are promising to overcome these bottlenecks [65,66], comprehensive accomplishments to implement optics into computers have been done [67][68][69][70][71][72][73][74]. Figure 8.41 shows a concept of the 3D integrated optical interconnects within computers, which we expect to be the final goal of optical interconnects [12,52,[75][76][77][78]. Optical waveguide films, in which thin-film light modulator/PD flakes are embedded, are stacked together with films containing thinned LSIs.…”

“…Further options include flexible waveguides (e.g. [41]), the in-situ fabrication of beam shaping optics together with the waveguides, or 'self-organized lightwave networks' [42]. We have tackled this challenge with a novel concept that allows to passively position components with a precision of a few µm on a printed circuit board.…”

Challenges for the introduction of board-level optical interconnect technology into product development roadmaps

Optical interconnects have gradually replaced electrical interconnects in the long-distance telecom, local-area, and rackto-rack link classes. We believe that this transition will also happen in the card-backplane-card datacom link class, both for bandwidth*length reasons and for density reasons. In analogy to the transition from individually wired boards to integrated printed circuit boards, we believe that eventually board-level optical interconnects will be based on an integrated technology such as board-embedded waveguides. In order to bring optical waveguide technology into mainstream product development plans, however, numerous challenges on many levels have to be met. Problems to be tackled span from the base level of materials (stability, processability) and devices (reliability, lifetime), over the subsystem level of packages (concepts, cost-efficient assembly and alignment) all the way up to the system level (link architecture, system packaging, heat management). A sustainable solution can only be reached if the development of all individual technology components is done with the whole system in mind. Important figures of merit are the cost per gigabit per second, the power per gigabit per second, and the maturity/reliability of the technology. We will give an overview of our optical interconnect activity, with respect to these challenges. We will discuss the options, explain our technology decisions and present some results of our multi-disciplinary activity.

a b s t r a c tSelf-organized optical waveguides formed in a photopolymer using two-photon photochemistry is proposed for self-aligned optical couplings involving nano-scale optical devices with wide tolerances in lateral misalignments. Simulations based on the finite-difference time-domain method revealed that on introducing a 400-nm write beam and a 780-nm write beam into the two-photon photopolymer respectively from two 600-nm-wide waveguides facing each other with 32 μm gap a self-aligned coupling waveguide called a two-photon self-organized lightwave network (SOLNET) is formed between the two waveguides. The lateral misalignment tolerance was found to be 3000 nm, which is five times larger than the misalignment limit of $ 600 nm in waveguides formed by conventional one-photon photochemistry. Preliminary experiments demonstrated that the two-photon SOLNETs are formed between multimode optical fibers by introducing a 448-nm write beam and a 780-nm (or 856-nm) write beam from the fibers into a photosensitive organic/inorganic hybrid material, SUNCONNECT s , with doped camphorquinone (or biacetyl).
