AbstractPhotonic integrated circuits (PICs) are an ideal platform for chip-scale computation and communication. To date, the integration density remains an outstanding problem that limits the further development of PIC-based photonic networks. Achieving low-loss waveguide routing with arbitrary configuration is crucial for both classical and quantum photonic applications. To manipulate light flows on a chip, the conventional wisdom relies on waveguide bends of large bending radii and adiabatic mode converters to avoid insertion losses from radiation leakage and modal mismatch, respectively. However, those structures usually occupy large footprints and thus reduce the integration density. To overcome this difficulty, this work presents a fundamentally new approach to turn light flows arbitrarily within an ultracompact footprint. A type of “photonic welding points” joining two waveguides of an arbitrary intersecting angle has been proposed and experimentally demonstrated. These devices with a footprint of less than 4 μm2can operate in the telecommunication band over a bandwidth of at least 140 nm with an insertion loss of less than 0.5 dB. Their fabrication is compatible with photonic foundry processes and does not introduce additional steps beyond those needed for the waveguides. Therefore, they are suitable for the mass production of PICs and will enhance the integration density to the next level.

Abstract Network-on-chip (NoC) is an efficient interconnection designing method for solving the limitations of buses in connecting IP cores. Power consumption is one of the most important issues in this area, solving this problem can lead to a more reliable and efficient design of NoC. Besides, there is another problem which is the More’s law is reaching an end. In this paper, we used a new approach, which improves designing points, so we can design NoC architecture more efficiently based on previous designs. Briefly, this method adds one step before the overall change of architecture which tests if the current design can be improved if we change some internal characteristics. For validation, we applied this method by using wire NoC, and changing its bottlenecks, and make them more efficient by using mapping and adding antennas for wireless communication. While this method seems simple at the first sight, but the result can help many designing, which are vital for industries, and technologies like Wireless Sensor Networks (WSN) and Internet of Things (IoT) devices. Briefly, this method can be used in NoC architectures and make them more efficient in a new style for new purposes. The results compared with the basic designing method with the new improved method; power and Energy improvements are respectively 25% and 46% with mapping and wireless improvements and approximately 60% more than traditional NoC in comparison with the basic method in this approach. This method also paves the way for green computing by avoiding producing more chemicals and products from a reusability perspective.
