✦ Synopsis

Ž gain. We observe a much lower signal gain seven times . smaller for this region relative to the anomalous region. Therefore, our results indicate that, when the pump waves are located in the anomalous GVD region, the signal gain is much greater relative to the normal GVD region.

IV. CONCLUSIONS

We have studied the efficiency of energy conversion from two pump waves into a weak signal. We demonstrated a maximum conversion efficiency of ;20% of the available power in DSFs. The experimental and numerical results are in good agreement, both showing that the efficiency of conversion is limited by pump depletion. We verified numerically that the maximum conversion efficiency would increase to ;40% for Ž . strictly monochromatic zero-linewidth lasers.

The proposed DR antenna has wide bandwidth with enhanced gain. The experimental density of the DR material used in the proposed rectangular DRA is only 4.04 g/cm 3 . Hence, the weight of newly constructed antenna is also comparatively low. Moreover, the high-dielectric-constant material ( r ϭ 48), h
