Tunable storage of optical pulses in a tailored Bragg-grating structure

Abstract

Scenarios for controllable creation, trapping and holding of single and multiple solitons in a specially designed nonlinear Bragg grating (BG) are proposed. The setting includes a chirped BG segment, which is linked via a local defect to a uniform BG with a built-in array of defects. A parabolic relation between the trapping position of the incident soliton and its power is obtained. Simultaneous trapping of two and three solitons at different locations is demonstrated too.Comment: 7 pages, 7 figures, 38 conferences, J. Opt. Soc. Am. B, in pres
