Abstract
A novel polymer-modified PbS quantum dot (QD) optical fiber amplifier was proposed and demonstrated. It was fabricated by depositing a PbS QD doped film around the tapered single mode fiber (SMF) coupler. The PbS QDs were synthesized in an organic phase and then transfer into water by polymer modification. A 1550 nm semiconductor light emitting diode as the signal source and a 980 nm laser diode source as the pump were injected into the fiber coupler simultaneously. Through evanescent wave excitation, we obtained a significant gain of about 6dB within the wavelength range between 1450 and 1650 nm.
