Three-Dimensional Optical Network-on-Chip (3D ONoC) has recently emerged as a high-performance on-chip communication solution; however, owing to the intrinsic characteristics of photonic devices in existing 3D ONoC, the insertion loss caused by undesirable coupling among optical signals degrades network performance. Considering manufacturing defects and unpredictable noise sources that cause the failure of Optical Routers (ORs) in 3D ONoC, previous work simply abandoned the disabled OR when computing the restore path. In this paper, we propose a new OR structure that reduces insertion loss, and we present the design of a novel adaptive routing algorithm, FTRA-BL, based on the new OR structure with bidirectional waveguides, without abandoning any disabled ORs. Our FTRA-BL selects the normal waveguide in the disabled OR as the backup link so that the best macroscopic restore path can be guaranteed. Simulation results show that our method performs better than previous work in improving transmission reliability and latency.
