Methods and apparatus are contemplated for multiplexing and de-multiplexing modulated optical signals using dispersion. Optical signals comprising a wavelength-multiplexed plurality of modulated spectra may be additionally multiplexed and de-multiplexed using dispersion. Dispersion multiplexing may be used in the simultaneous two-way propagation of optical signals over a waveguide.

Multiplexing and de-multiplexing optical signals

Method and apparatus for a Passive Optical Network (PON) to operate at significantly higher data rates than the prior art Passive Optical Networks.

Method and apparatus for multirate transmission in a passive optical network

Methods and apparatuses are contemplated for sharing optical sources in an optical network, which typically reduces the number of optical sources needed to operate the optical network.

Network with shared optical sources

Method and apparatus are contemplated for electrical-to-optical conversion coupled to an electrical switching fabric, wherein the number of lasers supplying optical carrier beams in electrical-to-optical conversion is less than the number of optical modulators. Cost savings for a reduced number of lasers may be considerable. Further, the shared laser bank supplying optical carrier beams may comprise shared control and monitoring electronics, resulting in a further cost savings. The shared laser bank may comprise at least one redundant laser. Optical modulators may be grouped into modules for ease of replacement and further cost savings. Optical signal conditioning may be applied to the lasers, and the conditioned beams may be shared among the modulators. Soliton pulses may be generated at a desired data rate, distributed to form a plurality of distributed pulse trains, and each pulse stream may be modulated with information from the same or different information channels.

Method and apparatus for cross-connecting optical transmission signals

Methods and apparatus are contemplated for dropping and adding a user-chosen wavelength sub-band in a band of wavelengths. Methods and apparatus are contemplated for separating and dropping individual wavelengths from a wavelength sub-band, and adding the individual wavelengths back to the wavelength sub-band. An OADM is contemplated that combines a wide-band OADM stage and a narrow-band OADM stage.
