A bi-directional, redundant, optical transport system is configured to provide a non-blocking, bi-directional, multi-channel, protocol independent optical transport system for the simultaneously transfer of digital, analog, and discrete data between a plurality data terminal equipment. The optical transport system includes a light transmission line for transmitting light bi-directionally and a plurality of nodes, connected in series by the light transmission line for receiving, extracting and passing signal light. Each node comprises: data terminal equipment for issuing and receiving electrical signals; an electro-optical interface device, associated the data terminal equipment, for converting electrical signals issued by the associated data terminal to signal light for insertion onto the light transmission light and for converting signal light, extracted from the light transmission line into electrical signals to be received by the associated data terminal; a translation logic device connected between the optical interface device and the data terminal equipment, for performing required protocol translation for the data terminal equipment and an optical interface device, connected to the electro-optical interface device and the light transmission line, for extracting signal light from the light transmission line to be converted into electrical signals by the electro-optical interface device for recipient by the data terminal equipment, for inserting, onto the light transmission line, signal light received from the electro-optical interface device and for passing signal light bi-directionally on the light transmission line.

Optical transport system

An optical network provides a digital interconnect fabric allowing nodes to seamlessly communicate with each other. Each node is connected to a bi-directional optical bus through passive optical interface devices. The optical interface devices route signals from each node onto the bus in both directions and also route signals traveling along the bus in either direction to each node. The optical interface devices and optical bus are passive and do not involve any regeneration of the electrical signals. The nodes are assigned wavelengths of transmission and have tunable receivers for selecting a wavelength of reception. The digital interconnect fabric facilitates Ethernet, Fibre Channel, and other digital communication protocols.

Methods and systems for creating a digital interconnect fabric

A system and method for quantizing a photonic signal involves passing the photonic signal through a photonic crystal. The photonic crystal has localized defects for splitting the photonic signal into a plurality of quantized photonic components and for directing the quantized photonic components to a set of optical detectors. A digital conversion of the photonic signal can occur by performing a threshold comparison of the quantized components, either in the electrical domain through comparators or in the optical domain through optical limiters.

Photonic analog-to-digital converters using photonic crystals

A communication system includes an optical 'LAN' () interconnecting a plurality of information sources () and sinks () with a light-to-electrical converter () associated with an electrical RF transmitters () and an RF-to-light converter () to a receiver (). The transmitter is coupled by way of electrical-to-light converter (), and the receiver is coupled by way of light-to-electrical converter (), and by way of a directional coupler (), to an end of an optical bus (), so that light signals representing signals to be transmitted flow in one direction, and light signals representing received signals flow in the other direction through the bus. A directional coupler () at the other end of the optical bus routes the transmit light signals to a light-to-RF converter () which feeds a sink or antenna (), and received signals from a source or antenna are routed by way of an RF-to-light converter () and the directional coupler () onto the optical bus ().

The method may also include forming a second clad layer outwardly from the optical waveguide, and forming a metal layer outwardly from the second clad layer. In lieu of injection molding, stamping may be performed to form the core layer of the optical waveguide.
