Abstract:
1. A fiber optical parametric oscillator comprising: a microstructure fiber having a first end and a second end; a pump wave input to the first end of the microstructure fiber; a reflective mirror for reflecting a wave from the second end of the microstructure fiber back to the microstructure fiber; a diffraction grating tuned to reflect a signal wave of a particular wavelength; a beam splitter disposed between the first end of the microstructure fiber and the diffraction grating, the beam splitter passing the pump wave to the first end of the microstructure fiber, the wave being reflected by the reflective mirror back through the microstructure fiber, the microstructure fiber generating a signal wave and an idler wave that are directed from the first end of the microstructure fiber to the diffraction grating by the beam splitter, the diffraction grating reflecting a signal wave of the particular wavelength back to the beam splitter and from the beam splitter back to the microstructure fiber, and the beam splitter passing a portion of the signal wave to an output of the parametric oscillator.
