Modeling quasi-phase-matched electric-field-induced optical parametric amplification in hollow-core photonic crystal...

Laser sources in the short- and mid-wave infrared spectral regions are desirable for many applications. The favorable spectral guidance and power handling properties of an inhibited coupling hollow-core photonic crystal fiber (HC-PCF) enable nonlinear optical routes to these wavelengths. We introduce a quasi-phase-matched, electric-field-induced, pressurized xenon-filled HC-PCF-based optical parametric amplifier. A spatially varying electrostatic field can be applied to the fiber via patterned electrodes with modulated voltages. We incorporate numerically modeled electrostatic field amplitudes and fringing, modeled fiber dispersion and transmission, and calculated voltage thresholds to determine fiber lengths of tens of meters for efficient signal conversion for several xenon pressures and electrode configurations.
