Abstract:
1. An optical system comprising: an optical coupler adapted for receiving and coupling pump radiation from a plurality of pump radiation sources, wherein a transmission of the optical coupler is periodic in radiation wavelength with a period Δλ; a pump-signal combiner optically coupled to the optical coupler and receiving pump radiation from the optical coupler, the pump-signal combiner adapted for coupling pump radiation from the optical coupler with optical signals; a plurality of pump radiation sources coupled to the optical coupler, wherein optical wavelengths of the pump radiation sources correspond to the periodic transmission of the coupler, and wherein at least one system parameter is adjusted to compensate for the optical wavelengths of the pump radiation sources corresponding to the periodic transmission of the coupler, wherein the at least one system parameter being adjusted includes the wavelength spacing Δλ of transmission maximas of the coupler and adjusting the optical wavelengths of the pump radiation sources to correspond to the adjusted wavelength spacing of the coupler.
