Abstract
The present invention provides a structure for Raman amplification of signals with counter-propagation of signal and pump and wavelength control while permitting broad bandwidth within each Raman order. The broadband optical amplifier of the invention combines Raman amplification with a circulator loop cavity and/or chirped Bragg gratings to achieve bandwidth performance improvements. The beneficial properties of the circulator loop cavity and/or chirped Bragg gratings can also combined with noise dampening property of the Sagnac Raman cavity.
