Abstract: Described is a method for designing individual stages of a multiple cascaded etalon TDC device to allow continuous thermo-optic tuning over a desired range without inducing incremental signal distortion due to uncontrolled and unpredictable dispersion of the TDC during tuning. This allows the signal to transmit without encountering periods of incremental distortion or dark spots. The method includes prior knowledge of each etalon stage, after full assembly, for spectral group delay profile as a function of temperature through modeling and/or characterization. Characterization can account for performance variations that are due to allowed manufacturing tolerances.

Abstract: A tunable dispersion compensator (TDC) is tuned from a first dispersion setpoint to a second dispersion setpoint while maintaining continuity of the dispersion. The dispersion tuning follows a pre-determined trajectory in the time domain, so that continuity of the optical dispersion across the channel optical bandwidth is maintained while minimizing all other TDC-induced optical impairments during a tuning period.

Abstract: One embodiment sets forth a technique for measuring chromatic dispersion using reference signals within the operational range of amplifiers used to refresh data signals. One red/blue laser pair in the transmission node is used for measuring dispersion and chromatic dispersion compensation is added at each line node in the system. Since reference and data signals propagate through each amplifier, the reference signals used to measure chromatic dispersion receive the same dispersion compensation (and will have the same residual dispersion) as the data signals. Therefore, any residual dispersion in the data signals will manifest itself in downstream dispersion measurements and, thus, can be corrected. The tunable dispersion compensator in each line node may be set to compensate for the measured dispersion, thereby compensating for both the chromatic dispersion of the link connecting the current node to the prior node and any uncorrected residual dispersion from prior nodes.

Abstract: One embodiment of the present invention sets forth a technique for determining properties of optical links using the amplified spontaneous emission (ASE) of integrated amplifiers. To calibrate the system, existing amplifiers in the nodes of the system can be operated in an ASE mode. A bypass switch at the mid-stage of each amplifier routes the ASE from the amplifier's first stage into one or more signal processing components, creating reference signals. Subsequently, the bypass switch routes the reference signals back into the mid-stage of the amplifier. After propagating through a link to the next node in the system, the optical parameters of the reference signals are measured and used to determine properties of the link, such as chromatic dispersion and attenuation. Tunable devices within the two nodes connected by the link may be set to compensate for specific properties of the link, thereby improving the quality of transmitted signals.
