摘要:
An apparatus includes a laser that includes an optical gain medium and first and second optical ring-resonators. The optical gain medium and the optical ring-resonators are serially optically connected together to form one or more segments of an optical cavity of the laser. One of the optical ring-resonators has a Mach-Zehnder interferometer forming an internal optical waveguide segment of the one of the optical ring-resonators.

Systems comprising at least an encoder for receiving a binary string of a data, the encoder adapted to partition the binary string into one or more binary substrings and assign a color to each one or more substrings corresponding to a color model a controller for converting the color into electrical pulses, a light source tor emitting the electrical pulses as pulses of colored light for transmission of the pulses through a communication channel. A parallel decoder may be included. The system is preferably coupled with a data compression system for compressing or decompressing binary data via a two bit partitioning scheme and replacing same with a compression key generated by the assembly of each packet with at least a second value for transmittal using the color mechanism above.

The invention discloses a device and a method for simultaneous full -duplex data and power transmission over a single optical waveguide. In this device, an optical waveguide connects a base station and a remote station. At the base station a high power laser source emits a first laser beam for carrying power and a base station low power laser source emits a second laser beam for carrying data from the base station to the remote station over the optical waveguide. The optical interface couples the laser beams into the optical waveguide for transmission. The first and second laser beams are received at the corresponding first and second remote station optical receivers. Similarly at the remote station, a third laser beam is emitted by a remote station low power laser source for carrying data from the remote station to the base station and this beam is received at the base station optical receiver. The wavelengths of the first, second and the third laser beams are distinct.

Systems and methods related to attachment of nomadic network nodes in a cellular communications network are disclosed. In one embodiment, a method of operation of a network control entity comprises receiving an attach request for attachment of a nomadic node to an anchor node, where the attach request comprises information indicative of one or more requirements of the nomadic node related to traffic and/or service demands. The method further comprises determining whether the one or more requirements of the nomadic node can be fulfilled with existing resources of a transport network that are allocated for the anchor node and, if the one or more requirements of the nomadic node can be fulfilled with the existing resources of the transport network that are allocated for the anchor node, sending, to the anchor node, an attach accept message to thereby accept attachment of the nomadic node to the anchor node.
