M. Ohyama et al., COMPACT 3-DIMENSIONAL OPTICAL INTERCONNECTS WITH LARGE TOLERANCE BY STACKED ARROW-TYPE WAVE-GUIDES, Electronics Letters, 30(12), 1994, pp. 951-952
A compact configuration of three-dimensional optical interconnects usi
ng stacked ARROW-B waveguides is developed. A short coupling length of
200mum and a large tolerance to core thickness are demonstrated.
