An all-fiber optical oscillator based on three nonlinear processes, namely stimulated Raman scattering and broadband and narrow-band optical parametric amplification, is presented and experimentally characterized. The wavelength tuning is achieved by means of the time-dispersion technique and spans over 160 nm. Through the same technique a fast tunable optical frequency comb has been realized exploiting cascaded four-wave mixing.

Abstract
An all-fiber optical oscillator based on three nonlinear processes, namely stimulated Raman scattering and broadband and narrow-band optical parametric amplification, is presented and experimentally characterized. The wavelength tuning is achieved by means of the time-dispersion technique and spans over 160 nm. Through the same technique a fast tunable optical frequency comb has been realized exploiting cascaded four-wave mixing.
