Abstract: A method and device are provided for fast, continuous tuning of an optical source. A first pump signal with a first pump frequency is input into a mixer along with a first seed signal having a first seed frequency. Within the mixer, the first pump signal and the first seed signal generate at least one idler having an idler frequency defined as two times the pump frequency minus the seed frequency. Shifting the pump signal across a frequency range at a sweep rate causes the idler frequency to be shifted by two times the frequency range at two times the sweep rate. The shifted at least one idler is mixed with the shifted pump signal to generate a first mix product that has two times the sweep rate and frequency range of the pump signal.

Abstract: A method is provided for measurement of dispersion or other optical and mechanical properties within a waveguide by inducing four-photon mixing at different locations within the waveguide by timing a pump signal to counter-collide with and abruptly amplify or attenuate one or both of a probe pulse and a signal pulse at each location. The measurement of the components of the resulting mixing signal created by each collision is used to calculate dispersion defined by the location at which the collision occurred. By combining the measurements from all of the locations, a spatial map of dispersion or other optical or mechanical properties within the waveguide can be generated.

Abstract: A system and method for increasing spectral efficiency, capacity and/or extending dispersion-limited reach in a communication link employs narrow filtering of a baseband signal to reduce the original bandwidth to a substantially smaller bandwidth for transmission across a transmission medium such as an optical fiber. By restricting the bandwidth, the rate of spreading is reduced significantly. The receiver at the other end of the transmission medium includes an equalizer for returning the received signal to its original bandwidth for retrieval of information contained in the signal.

Abstract: A high confinement nonlinear optical fiber is provided along with methods of parametric amplification for use thereof. The nonlinear optical fiber may include a plurality of concentric layers which are configured to provide different guiding regimes to low-frequency and high-frequency components through transverse geometry and refractive index profiling, thus reducing waveguide dispersion. The resulting optical fiber provides a parametric device with phase-matching in any spectral region of interest, such that a fiber optic parametric amplifier (FOPA) implementing the optical fiber can amplify in any spectral window of interest. A narrow-band FOPA configured to minimize phase mismatching is also provided for use with the optical fiber, and may be implemented as a light source or a monochromator.
