Ultra-broadband optical amplification using nonlinear integrated waveguides.

ABSTRACT: Four-wave mixing is a nonlinear optical phenomenon that can be used for wideband low-noise optical amplification and wavelength conversion. It has been extensively investigated for applications in communications¹, computing², metrology³, imaging⁴ and quantum optics⁵. With its advantages of small footprint, large nonlinearity and dispersion-engineering capability, optical integrated waveguides are excellent candidates for realizing high-gain and large-bandwidth four-wave mixing for which anomalous dispersion is a key condition. Various waveguides based on, for example, silicon, aluminium gallium arsenide and nonlinear glass have been studied^6-10, but suffer from considerable gain and bandwidth reductions, as conventional desi
