Patent Number Title Of Patent Date Issued
8032024 Method and apparatus for multi-band optical switching using multi-pump parametric devices October 4, 2011
A method of multiple-band switching using a multi-pump fiber parametric switch is demonstrated. The switching architecture combines parametric band amplification, wavelength conversion and selective signal conjugation, enabled by temporal control of at least one pump of the multi-pum
7764423 Polarization-independent four-wave mixing in a birefringent fiber July 27, 2010
A two-pump optical parametric device (OPD) having a nonlinear birefringent fiber, in which various four-wave mixing (FWM) processes can occur. The OPD applies, to the nonlinear birefringent fiber, two pump waves, each polarized at about 45 degrees with respect to a birefringence axis of
7630126 Two-pump optical parametric devices having reduced stimulated Raman scattering noise levels December 8, 2009
Two-pump optical parametric devices (OPDs), and methods of operating the same, generate desired output signals and idlers having reduced stimulated Raman scattering (SRS) noise levels. When the two-pump OPD is used as a two-pump optical parametric amplifier (OPA), the pumps are polar
7483203 Phase-sensitive amplification in a fiber January 27, 2009
A method of and device for generating an amplified optical signal directly in an optical fiber by way of phase-sensitive amplification based on one or more four-wave mixing (FWM) processes. In one embodiment, an input signal and two pump waves are applied to a highly nonlinear fiber (HNL
7436580 Optical buffer employing four-wave mixing October 14, 2008
An optical buffer employing Bragg scattering (BS), in which two pump signals are combined with an input (data) signal in a four-wave mixing (FWM) medium to frequency convert the input signal into an idler signal, which is applied to a dispersive medium, in which the idler signal prop
7324759 Method and apparatus for reducing phase jitter in an optical communication system January 29, 2008
Method and apparatus for transmitting a light signal in an optical transmission system is described. In an example, an optical transmission link includes an input port and an output port. The optical transmission link is configured to propagate optical pulses from the input port to the
7304788 Translation of individual and entangled states of light by four-wave mixing in fibers December 4, 2007
Optical frequency conversion by four-wave mixing in a fiber is considered. If the frequencies and polarizations of the waves are chosen judiciously, four-wave mixing enables the translation of individual and entangled states, without the noise pollution associated with parametric amp
7164526 Parametric amplification using two pump waves January 16, 2007
An optical parametric amplifier (OPA) driven with at least two pump waves. The pump waves may be configured such that the OPA produces uniform exponential gain over a range of wavelengths that extends, for example, at least 30 nm on either side of the average pump-wave wavelength. In
7062176 Nonlinear phase-shift compensation method and apparatus June 13, 2006
A nonlinear phase-shift compensation method and apparatus is provided for improving system performance in optical transmission systems. The apparatus includes a phase-shift compensating device that provides a partial compensating phase shift to reduce the nonlinear phase noise result
