Abstract
We investigate using a carbon nanotube (CNT) based photoconductive device for autocorrelation measurement. The device shows superior signal level (more than double) for optical powers less than 100μW compared to similar devices fabricated on semi-insulating GaAs and InGaAs. This device can be used to align, characterize, and monitor beams of ultrafast pulses within the nanowatt range of average optical power. This also allows a nondestructive method to study delicate CNT samples with nanofeatures.
