Energy compensated mode in a waveguide composed of lossy left-handed metamaterial

We reveal that stimulated Raman process can be one of the effective ways to compensate the energy loss intrinsic to the optical modes in waveguides composed of left-handed metamaterial. We evaluate the effect of the energy compensating process by using the guided mode’s wave functions multiplied by the envelope functions, which describe the stimulated Raman energy compensating process. Such an evaluation shows that the energy of the optical signal mode in the waveguide with lossy left-handed media can successfully be compensated.
