Quasi-phase-matched electric-field-induced optical parametric amplification in xenon-filled hollow-core fibers

摘要

Coherent light sources in the short- and mid-wave infrared spectral regions have many applications. We introduce a compact, hollow core fiber-based, quasi-phase-matched, electric-field-induced optical parametric amplifier (OPA). We numerically and analytically compute the spatially varying electrostatic fields within the pressurized xenon-filled core, which result from patterned electrodes with modulated voltages. We incorporate electrostatic fields, numerically modeled fiber transmission, and voltage thresholds into high fidelity modeling of OP A conversion efficiency. The required tens of meters of fiber are wrapped between two cylindrical sets of printed electrodes for experimental characterization of the OPA design.
