Light trapping in a fiber grating defect by four-wave mixing.
We propose the use of nonlinear four-wave mixing as a means of trapping light in a defect state in a nonuniform fiber grating. The amount of energy deposited is estimated by use of an approach similar to Fermi's "golden rule" and is approximately 30 fJ for realistic grating parameters and a pulsed pump of 100-ps width.
