20110274431APPARATUS AND METHOD FOR CONTROLLING A DYNAMIC GAIN EQUALIZER - Consistent with the present disclosure, a method and apparatus for providing a uniform spectral gain of an optical amplifier is provided. Namely, a “balancing” step is carried out in which an optical channel having the lowest power level input to an optical circuit, such as an dynamic gain equalizer (DGE), is assigned a zero “attenuation error” and is substantially un-attenuated by the DGE. The lowest power level optical signal does not require further attenuation and effectively serves as a reference power level, which the power levels of the remaining optical signals are set to. For example, remaining optical signals are assigned either positive or negative attenuation errors relative to the zero attenuation error based on optical signal input powers to the DGE and accumulated DGE attenuations over time. Those optical signals having a negative attenuation error are substantially unattenuated by the DGE, because such optical signals are adequately attenuated and do not require further attenuation. On the other hand, the DGE is controlled to attenuate those optical signals having positive attenuation errors to thereby flatten the output spectrum of the amplifier. In one example, interpolation techniques may be employed to control those portions of the DGE (e.g., attenuators or pixels) that do not receive a channel, such that adjacent pixels that receive channels may impart a desired amount of attenuation. In addition, further interpolation may be provided to appropriately control the DGE pixels, if the number of channels supplied to the DGE is different than the number of pixels of the DGE.11-10-2011

20110235164METHOD AND APPARATUS FOR CONTROLLING AN OUTPUT OF AN OPTICAL AMPLIFIER - A system is provided that includes optical amplifiers provided upstream from an optical add-drop multiplexer (OADM). One of the optical amplifiers may be a Raman amplifier that supplies amplified light to another optical amplifier, such as an erbium doped fiber amplifier (EDFA), which, in turn, further amplifies and feeds the light to an input of the OADM. During turn-up, for example, the EDFA may initially be disabled, the power of the pump lasers of the Raman amplifier may be gradually increased until light input to the EDFA exceeds a power threshold at which the EDFA can amplify the input light. Light supplied to the EDFA does not have an excessive amount of power. Accordingly, at this point, the gain of the EDFA may be appropriately adjusted and then activated to supply optical signals to the OADM. Such optical signals may have a low power but not too low so as to prevent proper operation of downstream EDFA. Moreover, these optical signal do not have power that is so high as to cause “spiking.” As a result, cross-talk with optical signals added by the OADM is minimized, and such added optical signals may be sufficiently amplified by optical amplifiers downstream from the OADM.09-29-2011
20110305459OPTICAL AMPLIFIER - Consistent with the present disclosure, an optical amplifier is provided that is configurable in one of two modes. In both modes, the optical service channel (OSC) may be dropped and converted to an electrical signal. In the first mode, the electrical signal is subject to further processing and the monitoring and/or control information carried by the OSC may be updated with new data. Such updated monitoring and control information is then supplied to an OSC transmitter and modulated onto an OSC output from the optical amplifier. In a second mode of operation (“loop back” mode), however, the monitoring and/or control information bypasses the processing noted above is looped back to the OSC transmitter unchanged. Accordingly, OSC monitoring and control information or data can be rapidly passed through the optical amplifier with little delay. Moreover, the optical amplifier may be configured to operate in either the first or second modes by appropriately configuring a switch. Thus, a standard optical amplifier can be used as a both a line amplifier, in which OSC data is processed and updated, as well as a booster amplifier in which such updating does not occur, for example, but the OSC data may be propagated to other amplifiers with little delay.12-15-2011

20110198240Sensors and Methods for Detecting Organic Carbonyl Species - A method for detecting an organic carbonyl species involves exposing a metal oxide-free film of a polyaniline to an environment suspected of containing an organic carbonyl species, detecting a change in electrical conductivity and/or an optical or luminescent property of the polyaniline, and, correlating the change in electrical conductivity and/or optical or luminescent property to a presence of the organic carbonyl species in the environment. Further, sensors for organic carbonyl species are disclosed having a metal oxide-free film of a polyaniline supported on an electrically insulating substrate. The method and sensors provide a good balance between response time and sensitivity, being considerably faster than metal oxide and metal oxide/polymer based sensors, while having greater sensitivity than other polymer-based sensors.08-18-2011
