2 μm超宽带PbS量子点光纤放大器
2 μm ultra-broadband PbS quantum dots fiber amplifier
摘要
Abstract
To address the issues of narrow gain bandwidth and complex structure in current fiber amplifiers,a 2 μm ultra-wide-band PbS quantum dot fiber amplifier is fabricated.Firstly,PbS quantum dots with an average diameter of approximately 9.2 nm are synthesized through the organometrical approach and deposited on the surface of the optical fiber cone region by the optical deposition method.Subsequently,the PbS quantum dots coated in the conical region of the fiber are excited by a pumping light source to emit photons with the same wavelength as the signal light in the 2 μm band,thereby achieving the amplification of the optical signal.The test results indicate that the optical fiber amplifier can attain a gain of 10.1 dB within the band of 1 900～2 100 nm,and the gain bandwidth is approximately 200 nm.关键词
