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, and includes 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： The invention relates to a method for suppressing the formation of oxygen gas bubbles at the contact interface between a glass melt and a component of a glass melting arrangement with this component being made of a precious metal. This component is especially the precious metal lining of a feed channel. The characterization “precious metal” includes in this context: platinum, gold, rhenium, all other metals of the platinum group, the alloys of the above-mentioned metals and the above-mentioned metals and alloys in dispersion oxide enhanced form. The occurrence of gas bubbles at the phase boundary between precious metal and the glass melt has been known for some time without effective measures having been suggested up until now to improve significantly the quality and yield of the generated glass products, particularly because precious metal parts have to be arranged in the glass manufacture downstream of the usual purification devices with which gas bubbles can be removed from the melt. To solve the task resulting therefrom, it is provided in accordance with the invention that the part, which is made of precious metal, is electrically conductively connected to one or several electrodes which are arranged spaced from the part, which is made of precious metal, in the glass melt, and that a potential drop is generated between the electrode and the part made of precious metal so that a current flows.

摘要： A laser for generating an optical comb is disclosed having an active laser medium enclosed in a resonator, a launching coupler for coupling pump light from a pump source into the active medium, an output coupler for coupling out the generated laser comb, and at least one optical filter within the resonator for generating the comb. A filter for introducing a wavelength-dependent loss within the gain profile of the active medium is inserted in the resonator. As a result, the ring gain becomes unity over a wide range, and many modes of the comb start oscillating in the resonator.

摘要： Optical communication networks (NET) transmit bidirectionally information between a center (OLT) and a plurality of optical network units (ONU) which are connected with each other by optical fiber links. The communication network (NET) of the invention operates with composite signals consisting of reference pulses and data packets which are transmitted in the time intervals between the reference pulses. The composite signals are transmitted to all optical network units (ONU). Each optical network unit (ONU) transmits its respective data stream to the center (OLT) using the asynchronous CDMA technique by modulating the received reference pulses with the respective data stream in an electro/optical unit (S1) and encoding the modulated reference pulses in a CDMA encoder (C1) using the CDMA technique.
