    摘要: A linear N×N robotic fiber optic switch is described. Notably, fiber adapters for connecting the input and output fibers are arranged linearly. Moreover, each fiber adaptor is driven by a push-pull mechanism such that it can be positioned to a front, center, or back position, with which the private plane of a fiber port can be separated from the other fiber ports and fiber connection can be configured using a simple linear translation robotic pickup free of interference in a compact space. Furthermore, a large scale fabric switch comprises 3 stages of N linear N×N robotic switches connected using fiber shuffles. Each stage or all three stages can share one robot to reduce cost. Scalability to large port counts may be accomplished proportional to N, the number of ports, rather than N2.

    摘要: An MCM may include a single optical routing layer that provides point-to-point connectivity among N chips in the MCM, such as all-to-all connectivity or full-mesh point-to-point connectivity. Moreover, the optical routing layer may include: N optical waveguides optically coupled to the N chips and a cyclic de-multiplexer, optically coupled to the N optical waveguides, that routes optical signals among the N optical waveguides without optical-waveguide crossing in the optical routing layer. For example, the cyclic de-multiplexer may include: an array-waveguide-grating (AWG) wavelength router and/or an echelle-grating wavelength router.

    摘要: Using silicon photonic components that support a single polarization, the output of an optical receiver is independent of the polarization of an optical signal. In particular, using a polarization-diversity technique, the two orthogonal polarizations in a single-mode optical fiber are split in two and processed independently. For example, the two optical signals are provided by a polarizing splitting grating coupler. Subsequently, a wavelength channel in the two optical signals is selected using a wavelength-selective filter (for example, using a ring resonator or an echelle grating) and combined at an optical detector (such as a photo-detector) to achieve polarization-independent operation.

    摘要: An integrated optical device includes a photo-detector (such as germanium) optically coupled to an optical waveguide. This photo-detector is deposited on the optical waveguide, and an optical signal propagating in the optical waveguide may be evanescently coupled to the photo-detector. In order to increase the absorption length of the photo-detector, a mirror (such as a distributed Bragg reflection grating) is included in the optical waveguide near the end of the photo-detector. This mirror reflects the optical signal back toward the photo-detector, thereby increasing the absorption of the optical signal by the photo-detector. In addition, absorption may be reduced by using electrical contacts that are electrically coupled to the photo-detector at locations where the optical mode of the optical signal is largely in the underlying optical waveguide, and by using a fingered metal layer to couple to the electrical contacts.

    摘要: An optical module is described. This optical module includes at least two optical devices that communicate with each other using edge-to-edge optical coupling of an optical signal between optical components in the two optical devices. Note that the edge-to-edge optical coupling may occur without mode converters at edges of either of the optical devices. Furthermore, the edge-to-edge optical coupling may be facilitated by an alignment substrate, which is mechanically coupled to the two optical devices. This alignment substrate aligns the edges of the two optical devices so that they are approximately parallel to each other, and aligns the optical components in the two optical devices.
