The potential of aerosol-synthesized single-walled carbon nanotube (SWCNT) films for silicon nitride photonic circuits is investigated in this study as a basis for developing integrated optics devices. By measuring the optical response of SWCNT-covered waveguides, the main SWCNT film parameters, such as absorption, nonlinear refractive, and thermo-optic coefficients, are retrieved, and the enhancement of all-optical wavelength conversion and the photoresponse with a 1.2 GHz bandwidth are demonstrated.
The integration of low-dimensional materials with optical waveguides presents promising opportunities for enhancing light manipulation in passive photonic circuits. In this study, we investigate the potential of aerosol-synthesized single-walled carbon nanotube (SWCNT) films for silicon nitride photonic circuits as a basis for developing integrated optics devices. Specifically, by measuring the optical response of SWCNT-covered waveguides, we retrieve the main SWCNT film parameters, such as absorption, nonlinear refractive, and thermo-optic coefficients, and we demonstrate the enhancement of all-optical wavelength conversion and the photoresponse with a 1.2 GHz bandwidth.
