✦ Synopsis

An efficient system for generating the four-wave mixing (FWM) effect in a short length of a highly nonlinear fiber (HNLF) is demonstrated using a ring configuration, which to our knowledge is the first of its kind to be reported. The conversion efficiency obtained is -4 dB for a HNLF length of 100 m when pumped with a 90 mW diode pump laser at 1490 nm in ring configuration which is the highest ever reported. The signal-to-noise (SNR) ratio is 43 dB. The conversion efficiency and SNR are flat over a span of 20 nm and can provide an effective means of wavelength conversion for telecommunication applications.

We demonstrate an all-optical wavelength converter using a ring cavity that produces conversion efficiency of more than unity within a certain bandwidth. The highly nonlinear fiber is used as the parametric amplifying medium and it is pumped by four independent pump lasers at 1427, 1443, 1461, and 1
