摘要： It is an object of the invention to make an optical receiver for an OCDM network addressable both individually and as part of a group of optical receivers. The optical receiver according to the invention is particularly characterized in that it comprises a series combination of two optical filters having different periods. One of the periods serves to receive broadcast signals. By selecting this period at the transmitting end, a group of optical receivers each incorporating a filter with this period can be selected and a data signal can be transmitted to this group simultaneously. The other period serves to control the reception of signals individual to each receiver, with the sum and/or the difference of the two periods being used for receiving the individual signals.

摘要： In OCDM systems, optical signals have hitherto been transmitted to the receiving end in the optical transmission channel assigned at the transmitting end. This type of transmission is rigid and makes possible only simple network topologies, such as, for example, point-to-point. The object of the invention is to make possible a flexible allocation of channels. The code converter according to the invention serves to convert an optical signal from a first optical transmission channel to a second optical transmission channel, comprises a first optical filter for filtering the first optical transmission channel, an optical broadband source and a second optical filter for filtering the second optical transmission channel.

摘要： It is an object of the invention to provide an OCDM system which minimizes interferences in the system and maximizes the data throughput in a simple manner. The OCDM system according to the invention is particularly characterized in that the send rate of optical packets to be transmitted in optical channels is different for different optical nodes of the OCDM system. Each node of an OCDM system is allocated one optical channel, for example. Also allocated are the send rates of optical packets to be transmitted in the optical channels, for instance by transmitting an individual frequency to the node.

摘要： It is an object of the invention to provide a coding mechanism for OCDM networks. At least a two step encoding is performed within the OCDM network on the way from a subscriber to a center or an optical ring. Encoding is performed at the combination points in the network, the two steps of the encoding process are geographically separated from each other. This reduces the number of required optical filter devices, since groups of codes can now be generated using a single filter device for the second encoding step. A simple tree-like network architecture has been chosen to demonstrate the basic idea. Application to other architectures is as well possible. If the coding filters are made reconfigurable the different channels in the network may be dynamically rearranged, e.g. into different groups to perform specific tasks as e.g. multicasting.
摘要翻译：本发明的目的是提供一种用于OCDM网络的编码机制。在从用户到中心或光环的路上，在OCDM网络内执行至少两步编码。在网络中的组合点执行编码，编码过程的两个步骤在地理上彼此分离。这减少了所需的光学滤波器装置的数量，因为现在可以使用用于第二编码步骤的单个滤波器装置来生成代码组。选择了一种简单的树状网络架构来演示基本思想。对其他架构的应用也是可能的。如果编码滤波器被重新配置，则可以动态地重新布置网络中的不同信道。进入不同的组以执行特定任务，例如。多播。

摘要： An inclusion of the liquid crystal in the direct vicinity of the core of an optical waveguide structured on a substrate allows to build a tunable optical device. The liquid crystal will be confined by replacing cladding material of that integrated structure. The tuning of the property of that liquid crystal i.e. its refractive index will influence directly the mode index of the core. This influence can be of such amount to allow to control the flow of optical signals transmitted through it. The tuning is advantageously achieved by applying some electric field via electrode on a segment of that core confined with liquid crystals.

摘要： It is an objective of the invention to reduce the technical complexity involved in the implementation of optical filters used in particular for the encoding and decoding of OCDM signals. It is also intended to simplify the tuning in order, on the one hand, to make the selection of the required transmission channels as simple as possible and, on the other, to be able at the receiving end to regulate the optical filter drift at the transmitting end for optimum reception. This object is achieved by an optical filter arrangement containing a first optical filter and a second optical filter connected in series or in parallel and with the second optical filter having an FSR adjustment range differing from the FSR adjustment range of the first filter. An advantageous effect is that the second optical filter facilitates fine tuning, with in particular the readjustment at the receiving end of optical filter drifts at the transmitting end being simplified.
