A Raman amplifier includes: a Raman amplification optical fiber configured to Raman amplify incoherent light in which relative intensity noise (RIN) is suppressed while transmitting the incoherent light; and a pumping light source configured to supply pumping light to the Raman amplification optical fiber. A corner frequency fc [Hz] at which the suppression of the RIN starts in the Raman-amplified incoherent light is estimated by using the following Equation (1): fc = 1 / ( D · Δλ · L ) ( 1 ) in which a full width at half maximum of a wavelength spectrum of the incoherent light is Δλ [nm], a length of the Raman amplification optical fiber is L [km], and a chromatic dispersion of the Raman amplification optical fiber at a center wavelength of the incoherent light is D [ps/nm/km].
A Raman amplifier comprising:
A method for designing a Raman amplifier including a Raman amplification optical fiber configured to Raman amplify incoherent light in which relative intensity noise (RIN) is suppressed while transmitting the incoherent light, and a pumping light source configured to supply pumping light to the Raman amplification optical fiber, the method comprising:
