【Abstract】 A Novel kind of wavelength filter and converter using nondegenerate four wave mixing (NDFWH) in an optical amplifier with tensile and compressively strained quantum wells (T/C SQW) was reported in this paper.The configuration of the T/C SQW converting filter was designed first,folowed by the establishment of the coupling model of the device.The influences of the property parameters of the optical amplifier with T/C SQW on the output efficiency,3 dB bandwidth,and the frequency shift were mainly discussed.The device can serve as both filter and wavelength converter with high conversion efficiency and narrow bandwidth on the order of 0.01 nm.Meanwhile,the frequency conversion range,which is decided by the gain bandwidth of the semiconductor media,is up to 5 000 GHz in the considered case.更多还原
