Integrated liquid core waveguides for nonlinear optics

摘要

A liquid core waveguide monolithically integrated with silica waveguides is demonstrated as a nonlinear optical device. Continuum generation is achieved using toluene as a core medium, with picosecond pulses at 1550 nm wavelength. A 500 nm wide spectrum is generated for an estimated peak input power of 60 kW over a propagation length of 16 mm.
