Abstract: The present invention is directed to an in- passband signaling method. The method includes the steps of extracting a control component and a data component from an optical signal. The control component may be used to determine the state of an optical switch in either a packet -switched network or circuit- switched network. The state of the optical switch is switched based on the extracted control signal. The control component may also be used to provide other network functions such as network operations, administration, and management (OA&M), network monitoring, and network control and management (NC&M). The control component is erased by polarization realignment of the optical signal. The control component is updated by remodulating the polarization state of the data component.

Abstract: The present invention relates generally to an optical CDMA transmission system and method employing differential optical encoding and bipolar decoding. Differential encoding and bipolar decoding may be performed at the bit level, wherein differential phase encoding and decoding occurs on an entire composite signal. Differential encoding and bipolar decoding may also be performed at the chip level, wherein differential phase encoding and decoding occurs on individual spectral components of a given signal.

Abstract: A system and method for transporting encrypted data having a transmitter and a receiver is provided. The transmitter generates a sequence of optical pulses, which are copied and output as identical channels. The identical channels are modulated by a plurality of modulators using data to generate a modulated data signal. Respective spectral phase encoders coupled to each of the plurality of data modulators encode respective modulated data signals using a plurality of mutually orthogonal phase codes that are individually associated with the respective spectral phase encoder. These encoded data signals are combined and code-scrambling by a spectral phase scrambler t using a scramble code as an encryption key to generate an encrypted signal. A receiver reverses the encryption to extract the data.
