The third‐order nonlinear optical property χ (3) I of a film of single‐walled carbon nanotubes was studied in the infrared region. The film combines a high χ (3) I (–0.85 × 10 –7 esu at resonant wavelength) with a rapid transmittance recovery (from differential transmission spectra, see Figure), making it suitable for highly efficient and ultrafast devices for optical telecommunications.
