- We prepared carbon nanotube (CNT)-incorporated sol–gel glass at a low temperature guaranteeing
homogeneous CNT dispersion and intact nonlinearity of the CNTs for ultrafast optic devices. Significant
defects and CNT agglomeration were avoided by optimizing the process steps, including stabilized CNT
dispersion in dimethylformamide and the gelation of silica sol. After verifying undamaged nanomorphologies
and optical properties of the enclosed CNTs via nonlinear absorption checks, we successfully
demonstrated all-fiber, mode-locked laser modulating the intracavity absorption with the CNT-incorporated
glass transferred onto a laser component. Resultant spectral width and repetition rate of the laser pulse
output were 1.1 nm and 2.96 MHz, respectively.
