NUMERICAL COMPARISON OF MULTI-PUMP RAMAN AMPLIFIERS BASED ON PHOTONIC CRYSTAL FIBER AND STANDARD SINGLE MODE FIBER
Keyword(s):
This paper presents a numerical analysis and comparison on the performance of multi-pump gain-flat Raman amplifiers based on triangular photonic crystal fiber and conventional fiber. It is demonstrated that the extra 5.93 dB Raman net gain can be achieved in the L-band when PCF acts as Raman gain medium. The noise performance of the two amplifiers are also calculated and compared. Comparison with the data of published literature was also carried out to verify our analysis. The results showed that PCF is the appropriate candidate for high gain Raman amplifiers.
