Abstract

We recently proposed and demonstrated a saturable absorber (SA) incorporating carbon nanotube (CNT). CNT-based SA offers several key advantages such as: ultra-fast recovery time, polarization insensitivity, high optical damage threshold, mechanical and environmental robustness, chemical stability, and the ability to operate at wide range of wavelength bands. Using the CNT-based SA, we have realized femtosecond fiber pulsed lasers at various wavelengths, as well as the very short-cavity fiber laser having high repetition rate. Besides the saturable absorption, CNT has been shown to have high third-order nonlinearity, which is also attractive for realization of compact and integrated functional photonic devices, such as all-optical switches and wavelength converters. In this paper, we first present photonic properties of CNTs, and review our studies on CNT-based mode-locked fiber lasers. We also refer to fabrication methods of CNT-based photonic devices. We show our recent research progresses on novel photonic devices using evanescent coupling between optical field and CNT.
