We investigate fiber optical parametric amplification (FOPA) in a structure of an As2S3 core and TeO2 cladding photonic crystal fiber (PCF). Various amplification features such as wavelength area, parametric gain value, and bandwidth are investigated. In order to design the FOPA system with optimal features, effects of different structural parameters variation on optical features of the PCF and parametric gain subsequently are also investigated numerically based on the finite-difference time domain numerical method. Using 15 cm of this fiber and a continuous wave pump laser of 1.1 W, we attain a gain spectrum of 350 nm with a maximum value of 37 dB around 1550 and 1310 nm, which are favored wavelengths in optical telecommunication systems. In fact, our structure ends in a wideband amplifier in an absolutely compact size, which is optimized exactly for optical telecommunication applications.

高非线性光子晶体光纤结构中的双频光纤参量放大

我们调查As2S3核心和TeO2包覆光子晶体光纤(PCF)的结构中的光纤光学参量放大(FOPA)。研究了各种放大功能,例如波长区域,参数增益值和带宽。为了设计具有最佳特征的FOPA系统,随后还基于有限差分时域数值方法,对不同结构参数变化对PCF光学特征和参数增益的影响进行了数值研究。使用15厘米的这种光纤和1.1瓦的连续波泵浦激光器,我们获得了350纳米的增益谱,在1550和1310纳米附近的最大值为37 dB,这是光通信系统中的首选波长。实际上,我们的结构以绝对紧凑的尺寸结尾在宽带放大器中,
