To　obtain　fiber　devices　with　large　stretched　amount,　we　designed　and　fabricated　two　kinds　of　chirped　fiber　Bragg　grating　(CFBG)　stretchers　with　the　phase　mask　inscription　technology.　According　to　the　theories　of　the　phase　mask　inscription　technology　and　dispersion　compensation　with　CFBGs,　the　fabrication　methods　for　the　two　stretchers　were　proposed　and　the　optical　paths　were　optimized　to　obtain　CFBGs　with　high　reflectivity　and　wide　reflection　bandwidth.　The　reflective　resonance　wavelength　of　CFBG　was　controlled　by　the　tension　sensor,　and　the　inscription　method　was　improved.　A　cascaded　CFBG　stretcher　with　large　dispersion　and　a　series　CFBG　stretcher　with　large　reflection　bandwidth　were　fabricated.　Fiber　sources　were　then　built　to　test　the　two　kinds　of　stretchers.　The　stretched　amount　provided　by　the　cascaded　CFBG　stretcher　was　directly　measured　to　be　345　ps,　which　was　consistent　with　the　theoretical　result.　The　stretched　amount　provided　by　the　series　CFBG　stretcher　was　indirectly　calculated　through　direct　and　reverse　connections.　The　calculated　result,　being　about　278.7　ps,　was　smaller　than　the　theoretical　result.
