ABSTRACT:
A pumped rare-earth fiber source wavelength control device, having source wavelength control effected by pump source wavelength and power control. The maintaining of pump wavelength and power control can be attained several ways such as by use of a wavelength sensitive coupler, a short length of fiber having an embedded grating, and a modulated grating embedded fiber.
