The possibility of high-density optical parallel transmission using an arrayed vertical-cavity surface-emitting laser (VCSEL) and an image fiber was demonstrated. Thirty six (6×6) laser lights from a VCSEL-array module were transmitted through an image fiber with a 460-μm diameter and consisting of 10,000 super-thin micro cores. The optical crosstalk was measured spatially and dynamically, and was less than -27 dB from dc to 3 GHz when a 1-m-long image fiber was used. We have actually transmitted bit data at a rate of 1 Gb/s, and the bit-error rate became 1×10/sup -8/ at the average received power of -27.7 dBm.
