一种新颖的WDM网波长转换器
A Novel Kind of Wavelength Converter for WDM-Nets
摘要
Abstract
A novel wavelength converter is proposed by use of D-fiber after periodically thermal/electric-field poling in the paper for the first time.The expressions for conversion efficiency η and bandwidth Δλ are derived,which are consistent with numerical calculation.The results show that η is proportional to the logarithm of second-order nonlinear coefficient and pump light power,and,however,they have only a little effect to Δλ.By properly increasing the length of D-fiber η can be efficiently enhanced,but Δλ will be decreased.Under the ordinary condition,η＞-15dB and Δλ＞100nm can be achieved.The wavelength conversion for 8-channel signal is simulated.关键词
