Abstract

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.

摘要

低维材料与光波导的集成，为增强无源光子电路中的光操控提供了充满前景的机会。在本研究中，我们探究了气溶胶合成的单壁碳纳米管（SWCNT）薄膜用于氮化硅光子电路的潜力，以此作为开发集成光学器件的基础。具体而言，通过测量覆盖有SWCNT的波导的光学响应，我们获取了SWCNT薄膜的主要参数，如吸收系数、非线性折射率和热光系数，并展示了全光波长转换的增强以及1.2 GHz带宽的光响应。
