Fabrication of SU8/SWCNT films as saturable absorbers

Abstract

We report the fabrication of novel SU8/SWCNT composite materials as saturable absorbes. The film can be easily inserted between two FC/APC connectors in order to have an inline saturable absorber. A passive mode-locked laser is created by placing this device in an Erbium doped fiber (L-band) ring cavity laser. The laser produces 871 fs pulses with a repetition rate of 21.26 MHz.
