  4. Abstract:
  5. This paper proposes a new optical network-on-chip which is scalable, low-power and high-performance. We design a centralized all-optical router which takes advantage of wavelength based structures. Our design achieves fully contention-free operation by utilizing path-based algorithms. By merging primary photonic switches and utilizing WDM technique, we mitigated the number of basic switching elements and thus reduced the consumed power down to 47.37% in comparison with the most prominent structure introduced for wavelength routing; i.e., the λ-Router. We obtained this superiority while maintaining the performance as high as the previous structures, which yields in energy savings. Moreover, our proposed network is traffic-independent and its routing algorithm is multicast-adaptive
