Fiber optic amplification includes a photonic crystal fiber coupled to a pump laser through a first coupler. The pump laser emits a first electromagnetic radiation wave into the photonic crystal fiber at a first oscillation frequency and a second electromagnetic radiation wave into the photonic crystal fiber at a second oscillation frequency equaling the first oscillation frequency. The first and second electromagnetic radiation waves interact to generate a signal comprising an electromagnetic radiation wave at a third oscillation frequency and an idler comprising a fourth electromagnetic radiation wave at a fourth oscillation frequency to be generated and amplified through parametric amplification. Parametric amplification is achieved by four wave mixing. The photonic crystal fiber emits a parametric output signal based on the four wave mixing. A nonlinear crystal frequency doubles the parametric output signal through second-harmonic generation.

Systems and methods are disclosed for splicing crystal fibers to silica glass fibers. Embodiments of the present disclosure provide mechanically stable bonds with negligible optical transmission loss by splicing fibers through a thermally enhanced reaction bonding process at lower temperatures than the melting point of the crystal. In an embodiment, mixing of the materials at elevated temperatures forms a stable intermediary material which enhances strength and reduces the transmission losses.
