TL;DR: In this article, the authors proposed an optical bridge for interconnecting optical networking components and methods of making optical bridges that include a waveguide that are compatible with semiconductor processing steps.
Abstract: The present invention provides an optical bridge for interconnecting optical networking components and methods of making optical bridges that include a waveguide that are compatible with semiconductor processing steps. The optical bridge of the present invention has less optical losses and is less affected by misalignment that prior art interconnections. The waveguide is formed of a curable optical material that spans optically active areas of two components. In one embodiment of the present invention, one optical component is an optical circuit board and the connected optical component is an electro-optical integrated circuit package containing light emitting or light receiving elements. The method provides a curable optical liquid to the components, bringing the components together to form a continuous optical liquid between the components, and curing the optical liquid.

TL;DR: A model that considers several physical impairments in all-optical networks based on optical signal-to-noise degradation and shows the impact of each impairment on network performance in terms of blocking probability as a function of device parameters is proposed.
Abstract: We propose a model that considers several physical impairments in all-optical networks based on optical signal-to-noise degradation. Our model considers the gain saturation effect and amplified spontaneous emission depletion in optical amplifiers, coherent crosstalk in optical switches, and four-wave mixing in transmission fibers. We apply our model to investigate the impact of different physical impairments on the performance of all-optical networks. The simulation results show the impact of each impairment on network performance in terms of blocking probability as a function of device parameters. We also apply the model as a metric for impairment-constraint routing in all-optical networks. We show that our proposed routing and wavelength assignment algorithm outperforms two common approaches.

TL;DR: It is shown that the analytical models match the simulation results very well in the case of the centralized switch and the mesh network, and can significantly improve performance of a large mesh network.
Abstract: In this paper we study the benefits of wavelength translation in all-optical networks providing clear channel circuit-switching among users. We first establish approximate analytical models for a static-routing circuit-switched network with an arbitrary topology, both with and without wavelength translation. We then study performance of the non-blocking centralized switch, the mesh-torus network and the ring network, using the analytical models and simulation results. It is shown that the analytical models match the simulation results very well in the case of the centralized switch and the mesh network. The results of our study also show that the benefits of wavelength translation are marginal for the centralized switch and the ring network. On the other hand, the results show that wavelength translation can significantly improve performance of a large mesh network.
