20090174932OPTICAL AMPLIFIER BANDWIDTH ALTERATION - The alteration of the bandwidth of an optical amplifier. Before alteration, optical signals having a first set of wavelengths are provided through a gain medium of the optical amplifier. In addition, a first pump having a set of pump wavelengths is propagated through the gain medium to thereby amplify the optical signals. After alteration, optical signals having at least a partially different set of wavelengths are able to be optically amplified by coupling a second pump into the optical medium. The second pump is at least partially distinct from the first pump in that the second pump includes at least one pump wavelength that was not included in the first pump.07-09-2009
20090174933EFFICIENT DISCRETE AMPLIFICATION - An optical amplification mechanism that introduces optical pump(s) into one port of an optical circulator. The optical circulator directs the optical pumps from that port into another port that is coupled to the output of a gain stage. The optical pump(s) then pass from the output to the input of the gain stage while amplifying an optical signal passing from the input to the output of the gain stage. A residual amount of optical pump(s) that exits the input of the gain stage is reflected back into the input of the gain stage. The reflected optical pump(s) then further assists in the amplification of the optical signal. Other embodiments are also disclosed.07-09-2009
20090175628OPTICAL AMPLIFIER CAPABLE OF AMPLIFYING OPTICAL SIGNALS THAT TRAVERSE SEPARATE TRANSMISSION FIBERS - Optical amplification by combining two or more optical signals from separate optical fibers, amplifying the combined signal using an optical fiber, and separating the amplified signals into their constituent optical signals. The separated optical signals may then be sent further in the direction they had been heading before combination. This allows multiple optical signals to be amplified using a single optical amplifier, perhaps even in a single optical fiber. Although not required, the two optical signals may even be travelling in different directions.07-09-2009
20100103957FRACTIONAL RAMAN ORDER PUMPING IN OPTICAL COMMUNICATION SYSTEMS - An optical communication system includes a gain medium that receives optical signal(s) of one or more optical signal wavelengths. The system also includes pump source(s) that are capable of generating at least a first pump signal and a second pump signal. The first pump signal includes at least one integer Raman order wavelength that includes a Raman gain peak that is one stokes shift away from at least one of the one or more optical signal wavelengths. The second pump signal includes at least one fractional Raman order pump wavelength that includes a Raman gain peak that is a non-integer multiple of a stokes shift from each of the one or more optical signal wavelengths. Optionally, there might be one or more other pump signals that do not satisfy the criteria specified for the first pump signal or the second pump signal.04-29-2010

20090285584UNREPEATERED OPTICAL SEGMENT FOR USE WITH REPEATERED SERIES OF OPTICAL SEGMENTS - An optical communications network that includes an unrepeatered optical segment that optically couples a remote terminal to a branching unit optically coupled within a series of repeatered optical segments. The unrepeatered optical segment may be quite long through the use of Raman amplification and/or remote optical pumped amplifiers thereby extending the reach of the unrepeatered optical segment. The branching unit or one of the repeaters may optionally be configured, perhaps remotely, to perform Raman amplification.11-19-2009

20100181961ADAPTIVE POWER CONTROL FOR WIRELESS CHARGING - Exemplary embodiments are directed to wireless power transfer. A transmitter generates an electromagnetic field at a resonant frequency with a transmit antenna to create a coupling-mode region within a near field of the transmit antenna. The transmitter defines a beginning of a recurring period by on-off keying the electromagnetic field during a synchronization portion of the recurring period. During a power transmission portion of the recurring period, the transmitter couples portions of the electromagnetic field to different receive antennas of various receiver devices within the coupling-mode region. The transmitter also determines a power allocation within the recurring period for the various receiver devices disposed within the coupling-mode region and adjusts a power level of the near field radiation responsive to power requirements received from the receiver devices.07-22-2010

20100332819DIGITAL CONTENT ACCESS CONTROL - Control of access to at least one digital content is managed as a function of at least one access criterion. The digital content is transmitted to at least one terminal in the form a data stream. The access criterion is stored in the terminal as a function of an identifier. The terminal receives the data stream in association with a control message indicating the identifier. It then retrieves the stored access criterion as a function of the identifier received in the control message. Finally, it verifies whether the stored access criterion is satisfied in order, where appropriate, to authorize access to the content.12-30-2010
