A proposal of all-wavelength optical amplifiers

Abstract

We have shown the interesting results of the optical signal amplifications using a Gaussian pulse propagating within a nonlinear microring resonator system. Several Gaussian pulses with different center wavelengths, for instance, 400-1,500 nm are investigated using the designed system. Results have shown that the optical signal amplification using the nonlinear ring resonator is plausible. By using the input power of 2 W, the optical output of 15 W is achieved. The interesting aspect is that all Gaussian input wavelengths can be amplified which can be useful for other wavelengths in future communication. © 2009 Elsevier B.V. All rights reserved.
