摘要:
Various embodiments of the present invention are directed to photonic-based interconnects for transmitting data encoded in electromagnetic signals between electronic mosaics. In one embodiment of the present invention, a photonic-based interconnect comprises a first photonic node coupled to a second photonic node via a waveguide. The first photonic node (1202) is coupled to a first electronic mosaic (1208) and is configured to transmit electromagnetic signals encoding data generated by the first electronic mosaic (1208) to a second electronic mosaic (1210) and receive electromagnetic signals encoding data generated by the second electronic mosaic (1210). The second photonic node (1204) is coupled to the second electronic mosaic (1210) and is configured to transmit electromagnetic signals encoding data generated by the second electronic mosaic to the first electronic mosaic and receive electromagnetic signals encoding data generated by the first electronic mosaic. The bus waveguide (1206) is configured to transmit electromagnetic signals between the first photonic node and the second photonic node.
摘要:
An optical sensing catheter system for physiological measurements of vascular or arterial parameters at plurality of location deploys wavelength division multiplexing in a common optical fiber to communicate with each optical sensor. The sensors are preferably passive planar waveguide type devices disposed to interact with the environment external to the catheter or other medical device.

The specification and drawings present a new method and apparatus for a rotary hinge for transmitting an optical signal (e.g., comprising data) bi-directionally or uni-directionally from one part to another in an electronic device, wherein these parts can rotate relative to each other using the rotary hinge. The optical signal can be transferred from one side to the other side of the hinge independently from light transmitted in the opposite direction. A sending guiding element (e.g., an optical fiber or a light guide) can rotate around a common rotation axis permanently attached to the side sending the optical signal and the emitted optical beam is directed towards the common rotation axis. The receiving guiding element, which collects the optical beam, is concentrically in the centre (coinciding with the common rotation axis) of the receiving side and permanently attached to it.
摘要:
A multi-chip processor/memory arrangement (20) is shown which includes a plurality of modules (22), also referred to herein as chips. The modules (22) are interconnected there between by an optical interconnect structure (24) also referred to herein as optical interconnect fabric. The basic concept underlining the structure of the arrangement (20) is to position the processing elements and memory cells on the small chips (22) which are fabricated in mass production based on inexpensive technology, for example, 0.25 micron technology and interconnected with the optical interconnect fabric (24). Packaged with the optical interconnect structure (24), a plurality of inexpensive chips (22) provides sufficient performance but for a small fraction of the cost of the processor/memory argument implemented on a single large computer chips (0.065 micron chip).
摘要:
The invention provides an optical connector for connecting a user circuit to an optical backplane, in use the connector being adapted for mounting on a user circuit. The connector comprises an active or passive photonic interface through which optical signals may be transmitted and received between a user circuit and a said optical backplane; a primary aligner for engagement with a corresponding aligner on a backplane to ensure alignment of the optical interface with the backplane; and a support for supporting the aligner and/or the optical interface on the connector. The support is selected to enable relative movement between a user circuit to which the connector is connected in use and the aligner and/or the optical interface. The support is preferably a flexible printed circuit board.
摘要:
An optical link includes a polymer waveguide having a top cladding layer, a core polymer layer, and a bottom cladding layer, supported by a substrate, with mirrors and optical vias. The core polymer layer includes a polymer material having a nanoparticle filler with a particle size of less than one tenth the shortest wavelength of interest for the optical link. The optical links comprise individual, multiple or massively parallel channels in single or multilayer networks.
