| Abstract(in English) | Currently, board-level optical interconnection is anticipated as a promising technology to realize high-performance computing systems with high speed and low-power consumption. Hence, optical printed circuit boards (OPCBs) integrated with polymer optical waveguides are drawing much attention, in particular, intensive efforts have been made for developing crossed waveguides for solving the problem of the space limit on OPCBs. In general, those crossed waveguides have been composed of step index (SI) type core. However, the excess optical loss at the crossed area due to the light leakage has been crucial. In this paper, we propose to apply graded-index (GI) cores to such a crossed waveguide. We already confirmed the strong optical confinement effect of GI core, thus it is expected that GI core enables to decrease the light leakage at the crossed area, compared to the SI-core crossed waveguides. In fact, we calculate the light propagation loss in crossed waveguides with SI and GI cores by developing a ray tracing simulation program. It is found that GI core shows remarkably lower waveguide loss (0.19dB for 50-perpendicular crosses) than those of SI core (3.7dB). |
