摘要： A wavelength independent multi-section optical coupler having at least three optical couplers, and at least two differential phase cells. Each optical coupler has two waveguides forming a coupling region having a net coupling value. The coupling value for each coupling region of the at least three optical couplers is different than the coupling values of the other two coupling regions. Each differential phase cell connects adjacent ones of said optical couplers. Each differential phase cell causes a differential phase shift in light signals traversing between the optical couplers, wherein the differential phase shifts of the differential phase cells, and the coupling value for each coupling region are chosen so as to minimize wavelength, and fabrication sensitivity of said wavelength independent multi-section optical coupler for a designed power splitting ratio.

摘要： Optical autodiscovery is provide between two optical modules to insure that when an optical signal is coupled between the two optical module, the optical signal from a first module does not interfere with operation of a second module. The autodiscovery is implemented by sending an optical identification signal from the first optical module via the coupling to the second optical module from which signal, the second optical module can verify and determined acceptance of the coupled first optical module. During this autodiscovery process, the optical identification signal from the first optical module may be attenuated or shifted in optical spectrum so as not to interfere with the operation of the second optical module. Autodiscovery may also be employed in cases where a first optical module is to receive an optical signal from a second module.
摘要翻译：在两个光学模块之间提供光学自动发现，以确保当光信号耦合在两个光学模块之间时，来自第一模块的光信号不会干扰第二模块的操作。通过从第一光学模块经由耦合向第二光学模块发送光学识别信号来实现自动发现，第二光学模块可从该第二光学模块验证和确定耦合的第一光学模块的接受。在该自动发现处理中，来自第一光模块的光学识别信号可以在光谱中被衰减或移位，从而不会干扰第二光模块的操作。在第一光模块将从第二模块接收光信号的情况下也可以采用自动发现。

摘要： Consistent with the present disclosure, data, in digital form, is received by a transmit nodes of an optical communication, and converted to analog signal by a digital-to- analog converter (DAC) to drive a modulator. The modulator, in turn, modulates light at one of a plurality of wavelengths in accordance with the received data. The modulated light is then transmitted over an optical communication path to a receive node. At the receive node, the modulated optical signal, as well as other modulated optical signals are supplied to a photodetector circuit, which receives additional light at one of the optical signal wavelengths from a local oscillator laser. An analog-to- digital converter (ADC) is provided in the receive node to convert the electrical signals output from the photodetector into digital form. The output from the ADC is then filtered in the electrical domain, such that optical demultiplexing of individual channels is unnecessary.

摘要： The present invention provides a system, apparatus and method to compute a route through a network having both digital nodes and optical express-thru nodes. According to various embodiments of the invention, a network topology is generated in which both digital nodes, optical express-thru nodes, and optical nodes are identified, and both physical and virtual links between these nodes are mapped. The network connectivity is identified, at least in part, by broadcasting a local link state advertisement and optical carrier group binding information to neighboring nodes, which enables both physical and virtual neighboring nodes to be identified. Once a topology is generated, both physical and virtual link characteristics are analyzed to ensure link diversity for traffic through the network and load balancing functionality across the network.
