A novel, wide-range, high-speed, and tunable wavelength conversion scheme, 'a fiber Raman converter,' is proposed, in which an externally injected high power pump laser and the associated Stokes laser are used to assist the Raman conversion process of signal light coded with optical information. In order to get a large frequency difference between two carrier frequencies, this fiber Raman process is cascaded twice. However, since the common external pump laser can be used in two cascaded Raman processes as long as phase- matching conditions are attained, the entire configuration is still simple. We numerically demonstrate that wide-range wavelength conversion from 1.31 micrometer to 1.55 micrometer for optical fiber communication is feasible at up to 5 Gbit/s.
