Abstract

A novel PbS quantum dots (QDs) fiber amplifier based on SiO₂ Sol-Gel method was proposed. The QDs doped SiO₂ films was deposited onto a fused tapered fiber coupler based on standard single mode fiber (SMF). With a 980 nm wavelength laser diode (LD) as the pump, 1550 nm signal and 980 nm pump light waves were injected into the tapered region simultaneously, through the evanescent wave, we obtained the gain at 1576 nm wavelength as high as 5 dB. The proposed fiber amplififier can implement the property of a small, integrated, high output, low noise, high gain, low cost, which meet the need of the future of optical fiber communication system.
