A polarization-maintained, ultranarrow FBG filter with a linewidth of 1.3GHz

[摘要] References(10)Cited-By(6)A polarization-maintained ultranarrow FBG filter with a linewidth of 1.3GHz has been successfully fabricated by using a 15cm-long phase mask. A maximum reflectance of 65% and a side lobe suppression of 13dB were obtained by employing an apodization technique with slits.
