Direct MT™-compatible connectorisation of VCSEL and LED-arrays to plastic optical fiber ribbon for low cost parallel datalinks

For the realisation of MT(TM) compatible direct connectorised modules, a PMMA-based interconnection scheme, using index-alignment is developed. Plastic pieces are accurately positioned with respect to the chips and then fixed with epoxy, following an index-alignment strategy. Alignment accuracies in the range of 5 to 10 mu m have been achieved, which is sufficient to have good coupling efficiencies in view of the relaxed alignment tolerances when coupling to large core POF (120/125 mu m). The chips are assembled in commercially available packages, which are then mounted on PCB boards. First coupling measurements on fully assembled modules, using a red (670nm) 1x8 VCSEL-array and a 1x8 PC-LED (Resonant Cavity LED, 980 nm), are successfully carried out

Microcavity LED-based parallel data link using small diameter (125 µm) plastic optical fibers

Parallel optical data links using high efficiency Microcavity LEDs and small diameter POF ribbons are proposed. MCLED performance, coupling efficiencies, alignment tolerances, POF end facet termination techniques and first link experiments are studied
