Article Synopsis
- The photoelectric hybrid network aims to enhance chip multiprocessor (CMP) systems by providing ultra-high bandwidth, lower delays, and reduced power consumption.
- The Dijkstra algorithm is utilized to minimize transmission loss and decrease the output power of link transmitters in mesh-based optical networks-on-chip (ONoCs), leading to better performance.
- Simulation results show that this optimized power control significantly reduces power consumption while maintaining similar network performance compared to traditional methods, even as the network size increases.

Article Synopsis
- Optical networks-on-chips (ONoCs) offer high bandwidth and low latency for on-chip communication, but power loss and optical signal-to-noise ratio (OSNR) are critical challenges affecting their scalability and performance.
- The current dimension-order routing algorithm used in ONoCs results in significant power loss and crosstalk noise, prompting the need for improved routing methods.
- This paper introduces a 5×5 all-pass optical router model and a novel routing algorithm that minimizes power loss while optimizing OSNR, demonstrating successful results in reducing power loss and enhancing OSNR in larger network sizes (5×5 and 6×6).
Polarization switching (PS) between two orthogonal linearly polarized fundamental modes is experimentally observed in commercial free-running 1550 nm vertical-cavity surface-emitting lasers (VCSELs) (Raycan). The characteristics of this PS are strongly modified after introducing a polarization-preserved (PP) or polarization-orthogonal (PO) optical feedback. Under the case that the external cavity is approximately 30 cm, the PP optical feedback results in the PS point shifting toward a lower injection current, and the region within which the two polarization modes coexist is enlarged with the increase of the PP feedback strength.
