  • Patent number: 10302561
    Abstract: A center wavelength of first pulsed light (exciting pulsed light) is variable, and a pulse rate of the first pulsed light coincides with an integer multiple of a free spectral interval of an optical oscillator at a center wavelength of second pulsed light (signal pulsed light or idler pulsed light).

  • Patent number: 9557626
    Abstract: An optical apparatus comprising: a source and a loop. The source generates a pump. The resonating cavity of the source includes: a gain medium; and a tunable filter for selecting a wavelength. The loop comprises: an input coupler; a waveguide; and an output coupler. The input coupler receives the pump and a signal and outputs the pump and the signal into the waveguide In the waveguide, energy in the pump is transferred into energy in the signal while a relative center position of the signal is crossing a center position of the pump in a first direction while both are passing through the waveguide and into the output coupler. The output coupler r outputs a first portion of the signal and a second portion of the signal is fed into the input coupler as the signal, completing the loop.
