• Bragg gratings
• Linear chirp
• Linear negative tapered
• Bistability

Based on the coupled mode theory, the influence of the introducing chirp on the bistable characteristics of linear negative tapered Bragg gratings have been investigated. The results show that introducing positive chirp is helpful to improve the bistable performance of linear negative tapered Bragg gratings; and the bistable performance can be further optimized by reasonably selecting the length of the linear negative-tapered Bragg gratings with positive chirp.
