摘要： Methods and systems include generating one or more mid-infrared frequencies based at least upon electron transitions in one or more quantum cascade heterostructures. The quantum cascade heterostructures are concurrently configured with a significant second-order nonlinear susceptibility, a significant third-order nonlinear susceptibility, and an insignificant group velocity dispersion. A set of mid-infrared frequencies (that may include a frequency comb) is generated in the quantum cascade heterostructures based at least upon a four-wave mixing of the one or more mid-infrared frequencies. The four-wave mixing arises at least from the significant third-order nonlinear susceptibility and the insignificant group velocity dispersion. A set of terahertz frequencies (that may include a frequency comb) is generated in the quantum cascade heterostructures based at least upon a difference frequency generation from mid-infrared frequency pairs selected from the set of mid-infrared frequencies. The difference frequency generation arises at least from the significant second-order nonlinear susceptibility.

摘要： To a first nonlinear waveguide and a second nonlinear waveguide each having a refractive index which varies in response to the input of an optical signal, input optical signal pulses are inputted together with continuous light of a predetermined wave length said input optical signal pulses being caused to have a time delay corresponding to 0.6˜1.2 times the pulse width of said input optical signal pulses. Then, the phase of an optical signal outputted from the second nonlinear waveguide is adjusted to a predetermined amount with respect to the phase of an optical signal outputted from the first nonlinear waveguide, and the optical signal outputted from the first nonlinear waveguide and an output signal outputted from the second nonlinear waveguide are coupled, whereafter a wavelength component of the input optical signal pulse is removed from the coupled optical signal. Consequently, an output optical signal pulse of a wavelength different from that of the input optical signal pulse can be obtained while little wavelength chirping is generated.

摘要： An optical parametric diffuser is provided with an optical mixer which receives inputs of a probe light of a wavelength .lambda..sub.1 and a pumping light of a wavelength .lambda..sub.2, multiplexes them, and generates an output signal light including a wavelength .lambda..sub.5 which is apart from the pumping light wavelength on the opposite side of the probe light wavelength by n.DELTA..lambda. (.DELTA..lambda.=.vertline..lambda..sub.1 -.lambda..sub.2 .vertline., n.gtoreq.2). The signal of a wavelength .lambda..sub.5 is then extracted by a band-pass filter. The optical mixer is made to have a peak in output signal generation efficiency at the wavelength .lambda..sub.5 so that an output light beam of the wavelength .lambda..sub.5 can be obtained from the probe light and the pumping light.

摘要： The span of an optical dispersion-limited fiber for propagating optical pulses is improved by simultaneously chirping and amplifying the stream by means of a saturated semiconductor laser amplifier. The chirp causes a compression of the pulses as they propagate through an initial portion of the fiber, whereby the span of the fiber is increased.
