Abstract

Optical fibers with organic crystal cores have great potential for optical signal processing. The high nonlinear susceptibility in some organic materials,¹ combined with the waveguide advantages of tight field confinement and long interaction length, provides for efficient three-wave mixing interactions with the milliwatt output power of semiconductor lasers. Typical examples are optical parametric amplification, second harmonic generation (SHG), and logic operations. Additionally, phase matching can be achieved by having the different wavelengths in different fiber modes. Thus even materials, not phase-matchable as bulk crystals, can be used in waveguide form.
